Summary
The Myconid Grove
Early in their exploration beneath Garmok's Mine, the party came upon a vast bioluminescent cavern filled with glowing fungi and strange mushroom-like creatures. What Shade's Warlock Eye had initially scouted revealed itself to be home to a colony of Myconids—intelligent, peaceful fungal beings who tend their groves in the deep places of the world. The chamber was bathed in gentle, colorful light from countless bioluminescent mushrooms, with large fungi of various types growing throughout the space, including shriekers (alarm fungi) and violet fungus.
The Myconid Sovereign, leader of the colony, approached the party and released a cloud of rapport spores that settled over them, granting temporary telepathy. Through this telepathic link, the party could sense the Myconid's thoughts, feelings, and intentions as intuitive concepts rather than language. The Sovereign asked who they were and why they had come. When Karma explained they were Deez Nuts, on a quest to stop the dragon cult from raising Tiamat, and mentioned slaying the black dragon Voaraghamanthar, the Sovereign shuddered visibly. Through the telepathic connection, the party experienced the Myconid's traumatic memory—Voaraghamanthar had previously attacked their grove, destroying much of it and killing many adults and children.
The news that the dragon was dead filled the Sovereign with overwhelming joy and relief, emotions the party felt directly through the spore link. He released more spores throughout the cavern to share the news with his colony, then proudly presented his young sprouts (Myconid children) to the party as a gesture of trust and gratitude. The Myconids explained their ongoing problem: their cavern served as a major thoroughfare between the surface and the deeper Underdark, and creatures from below—raiders, traders, and worse—constantly passed through their peaceful grove. They wished for a way to be left alone but didn't know how to reroute the traffic or close off their cave. The party promised to investigate and see if they could help. The Myconids mentioned that others deeper in the tunnels might know more about the dragon and had helped repel it in the past, though the Myconids themselves didn't know what lay beyond their cave system.
Bidding farewell to the Sovereign and his colony, with a young Myconid sprout excitedly following them to the edge of the grove before being called back by its parent, the party ventured deeper into the tunnels. As they left the glowing fungal cavern behind, the tunnels grew darker, colder, and more oppressive. The carved dwarven passages gave way to natural caves—ancient formations untouched by tools, existing since time immemorial.
Battle with the Cloaker
As the party moved cautiously through the increasingly natural tunnels, danger struck from above. A Cloaker—a predatory aberration resembling a large manta ray or living cloak—dropped from the ceiling to attack Keyleth. The creature had been using its natural camouflage to blend perfectly with the stone ceiling, surprising the party when it suddenly unfurled and swooped down on the ranger.
Alexios and Xanphina rushed forward to protect Keyleth, while Shade unleashed eldritch blasts from the rear and Karma shifted into a more aggressive form. The Cloaker's moaning ability created phantasmal duplicates that confused the party's attacks, making it difficult to discern which image was the real creature. Despite this deception, the party's coordinated strikes brought down the aberration before it could inflict significant harm. Xanphina landed powerful blows with Garmok's Flail, while Alexios's radiant smites burned through the creature's unnatural hide.
The battle was brief but tense, and the encounter served as an ominous warning of what lurked in these depths. The deeper they went, the more aberrations they would face—creatures that didn't belong in the natural world, twisted by dark magic or ancient experiments.
The Mind Gobbler Appears
Shortly after the Cloaker battle, continuing deeper into the winding passages, the party caught their first glimpse of the creature they had come to find. In a distant chamber, illuminated by Shade's dancing lights and visible through the party's darkvision, stood the Mind Gobbler.
It was a horrifying sight: a massive, dragon-sized aberration with the body of an enormous turkey grafted with writhing tentacles, pulsing with visible psychic energy. The creature appeared to be the result of mind flayer experiments—combining a mundane beast with aberrant physiology and psionic abilities. Surrounding it were smaller creatures, gobble thralls enslaved by its psychic powers, moving in eerie synchronization with their master.
The party observed from a distance, taking in the full scope of the threat. The creature's tentacles twitched and coiled, its eyes glowed with unnatural light, and even from this range they could feel a faint pressure against their minds—the creature's passive psionic aura. They didn't engage yet, instead withdrawing quietly to gather more information and search for any advantage they could find before confronting such a formidable foe.
Ilyra the Drow Researcher
Before confronting the Mind Gobbler directly, the party discovered a side passage that led to a magically warded chamber. Here they met Ilyra, a drow woman who had been studying the aberrations in these tunnels for decades. She had sensed their presence through her magical wards and came to investigate, quickly realizing they were not hostile.
Ilyra's study was filled with books, scrolls, and arcane equipment, the walls humming with protective magic that kept out even the Mind Gobbler's psychic intrusions. She invited the party inside and offered them sanctuary, recognizing that they intended to face the creature she had been studying from a safe distance. The drow researcher explained that the Mind Gobbler was the result of mind flayer experiments—an ordinary creature transformed into a psionic aberration. She was unsure what the original creature had been, though she noted it was "certainly not a common turkey."
Ilyra had been studying the Mind Gobbler for years, carefully observing its behavior and capabilities while avoiding direct confrontation. She shared what she knew: the creature had existed in these tunnels for years, possibly decades, growing stronger over time. It seemed bound to its cavern—she had never seen it venture far from its lair. She mentioned that an aboleth might also lurk somewhere deeper in the mine, and there could be a connection between aboleths and mind flayer activity in this region.
Most importantly, Ilyra offered the party a weapon specifically designed to combat psionic creatures: a magical knife that disrupts psionic connections. If they could lodge the blade in the Mind Gobbler during combat, it would disrupt the creature's psychic abilities and potentially prevent its regeneration. The knife had been forged specifically for this purpose, though Ilyra herself had never dared to use it. She explained its mechanism in detail—the blade would sever the psionic threads the creature used to control its thralls and sustain itself, giving the party a critical advantage in battle.
Ilyra also shared information about the tunnel network. The passages to the south were closest to the surface, and deep gnomes (svirfneblin) were rumored to live in this network. The gnomes were masters of stonework and could potentially create a new exit—which would help the party escape and solve the Myconids' problem by creating an alternate route through the Underdark. She offered to create a *Scroll of Featherfall* for them, anticipating they would need to navigate vertical passages like the great chasm with the broken winch they had passed earlier.
Encounter with the Derro
Continuing their exploration with Ilyra's knife safely secured and armed with new intelligence about their foe, the party navigated deeper into the tunnel system. The passages led them to a chamber with a sharp drop-off—an enormous chasm descending into darkness. Even with darkvision, the party could not see the bottom. Along the wall, they discovered the remains of an old winch system, broken down and abandoned long ago.
As the party examined the chasm and the broken winch, they heard footsteps echoing through the tunnel. Rounding a corner on their phantom steeds, the party nearly collided with a group of Derro—dark dwarves native to the deep Underdark. The Derro merchants halted and turned to face the party warily.
The lead Derro, a gruff but businesslike trader, greeted them cautiously. "Well met. Where are you off to?" Alexios boldly declared they were heading to fight the Mind Gobbler. The Derro shook their heads at the foolishness of surface dwellers. The dark dwarves explained they were searching for a trade route from their city in the Underdark to the surface, hoping to establish commerce with surface dwellers. They noted they could not go through the Myconid territory—past conflicts had made that path too dangerous.
The Derro offered their wares for trade: mechanical goods including gears, chains, and oil. They mentioned they could repair the broken winch system if the party was interested. In exchange, they sought unique weapons or tools that would help them either find a new path to the surface or make it easier to navigate the dangerous routes they knew. Keyleth and Karma quietly expressed concern about helping the Derro find a route through the Myconid grove, not wanting to endanger their new fungal friends.
Gootcha suggested they could trick the Derro by giving them a fake magical item. Shade, with her high persuasion skill, offered to sell the deception. The party settled on offering a plain gold bracelet, claiming it helped locate gnomes—even when they turned invisible. This would theoretically help the Derro find the deep gnomes (svirfneblin) rumored to live in these tunnels, who could show them alternate routes.
But the Derro leader was no fool. He took the bracelet and cast *Identify* on it, the spell revealing its mundane nature. "It appears this bracelet doesn't do what you say it does," he said gravely, his eyes narrowing. Shade quickly covered, claiming they were swindled by merchants called "the Bronze Blades" (a name she invented on the spot). Keyleth and Karma nodded along, feigning embarrassment. Alexios, true to his oath of honesty, looked uncomfortable but didn't contradict the deception.
The Derro leader studied them for a long moment. "Since we just met, I am going to assume that you did not know this," he said slowly, handing the bracelet back. "It happens to the best of us. But it's a dangerous game you're playing." The party apologized profusely, and the Derro seemed bemused rather than angry. They hadn't heard of these Bronze Blades, but noted they sounded like dwarves worth trading with.
As the conversation wound down, Alexios—unable to let the Derro walk into danger—warned them that the direction they were heading led to certain death: the Mind Gobbler's lair. The Derro thanked him for the warning and agreed to go a different direction. Alexios tried one last gambit: "How about a little tit-for-tat? I give you that information. Can we trade for some of that equipment?" The Derro leader responded simply: "No." With that, the merchants shouldered past the party, not aggressively but firmly, and disappeared into the darkness of the Underdark tunnels.
The Mind Gobbler - Combat Begins
Armed with Ilyra's psionic disruption knife and prepared with intelligence about their foe, the party approached the Mind Gobbler's lair. The vast cavern opened before them, and in the center waited the massive aberration, surrounded by its gobble thralls. The party attempted to use Shade's *Pass Without Trace* spell to sneak closer, but the Mind Gobbler had heard the echoes of their conversation with the Derro or perhaps sensed their minds approaching. It turned to face them, tentacles writhing, and combat began.
Alexios charged forward, channeling Athena's divine fury and swearing his Vow of Enmity against the aberration. His flaming sword struck true, cutting deep into the creature's flank. Xanphina raged and followed, her ancestral spirits manifesting around her to protect her from psychic assault. She swung Garmok's Flail in devastating arcs, each hit reverberating through the cavern.
Keyleth and Karma unleashed ranged attacks from the cavern's edge—arrows and magical thorns striking the Mind Gobbler's thick hide. Gootcha positioned herself in shadows, her Raven Queen-blessed crossbow singing as phantom ravens swirled around her bolts. Shade stood back, her Bagpipes of Zariel's Lament wailing infernal music across the battlefield, weaving eldritch magic and bardic inspiration into a devastating combination that disrupted the Mind Gobbler's concentration while empowering her allies.
The Mind Gobbler responded with a *Psychic Gobble Burst*—a wave of psionic energy that slammed into Alexios and Xanphina. The paladin gritted his teeth against the mental assault, but Xanphina's ancestral spirits shielded her mind, her rage making her resistant to the psychic damage. The gobble thralls surged forward, tentacles lashing at the front line.
Alexios and Xanphina cut down the first wave of thralls, but more kept coming. The Mind Gobbler teleported across the chamber, appearing behind Karma and Keyleth. Gootcha wheeled and fired, her crossbow bolt striking the creature in its bulbous eye. It shrieked—a terrible sound mixing turkey gobble with psionic screaming—and teleported again, evading their attempts to pin it down.
The Mind Gobbler - Mythic Transformation
As the battle raged and the party pressed their advantage, Alexios's sword found what seemed to be a vital spot—the creature's heart, or where its heart should be. The Mind Gobbler staggered, wounded deeply, and for a moment the party believed victory was at hand. They were wrong.
The creature's body began to crack and pop, expanding grotesquely. Its tentacles multiplied before their eyes, its eyes glowed with intensified psychic power, and the grievous wounds began to close. The Mind Gobbler had entered its mythic phase—a second life granted by whatever dark experiments had created it. This was not a creature that could be killed easily.
The transformed aberration unleashed a *Mythic Gobble Quake*—a massive psychic shockwave that rippled through the cavern. Keyleth dropped unconscious instantly, the ranger's mind overwhelmed by the psionic assault. Karma rushed to her side, desperately feeding her a healing potion as the Mind Gobbler summoned fresh gobble thralls from the shadows of the cavern. The thralls seemed endless, rising from the darkness in waves.
Alexios found himself surrounded by thralls, their tentacles wrapping around his armor and trying to drag him down. Xanphina cleaved through them with Garmok's Flail, but more kept coming—the Mind Gobbler could apparently create them endlessly, spawning new servants as quickly as the old ones fell. Shade cast *Hypnotic Pattern*, trying to disable multiple thralls at once, but the Mind Gobbler's advantage on saving throws against magic allowed it to shrug off her spell with contemptuous ease.
Gootcha managed to lodge a crossbow bolt deep in the creature's skull, causing it to stumble. But even this grievous wound began to regenerate before their eyes, flesh knitting back together with disturbing speed. The Mind Gobbler's connection to this cavern seemed to sustain it—the very walls pulsed with aberrant energy, feeding power to their monstrous foe. Keyleth fell unconscious a second time despite Karma's healing, the repeated psychic assaults proving too much for the ranger's mind to withstand.
Xanphina Dominated
As the battle reached its most desperate moment, the Mind Gobbler turned its full psionic attention toward Xanphina. The creature's eyes glowed with malevolent psychic power as it unleashed its *Psionic Domination* ability directly at the barbarian. Despite her ancestral spirits' protection and her advantage on the Wisdom saving throw, Xanphina's dice betrayed her—she rolled a natural 1 and a 2. Her eyes glazed over as the Mind Gobbler's telepathic voice echoed in her mind with a simple command: "Protect me."
Xanphina turned toward her companions, Garmok's Flail still in hand, now under the aberration's control. The Mind Gobbler teleported 30 feet away from the front line, positioning Xanphina between itself and Alexios. The party faced a horrifying dilemma: their powerful barbarian ally was now their enemy, and they couldn't harm her without risking killing their friend.
Alexios desperately asked if breaking the creature's concentration could free her. The answer was yes—damage to the Mind Gobbler might force it to fail a Constitution save and release its hold. But with Xanphina now standing guard over the creature, getting close enough to strike would mean fighting through her first.
Karma had a brilliant idea: they had a *Bead of Force* from Garmok's Hoard. The bead would create an impenetrable sphere around Xanphina, trapping her safely inside where she couldn't hurt anyone—and couldn't protect the Mind Gobbler. Even better, the sphere would only weigh one pound regardless of what was inside it, meaning they could pick it up and carry Xanphina away from the battle entirely.
The party agreed this was their best chance. Karma threw the bead at Xanphina's feet. It exploded into a shimmering force sphere, encasing the dominated barbarian in what the party immediately dubbed the "hamster ball." Xanphina, still under the Mind Gobbler's control, pounded futilely against the inside of the sphere, unable to break through or fulfill her command to protect her master. The distance between her and the Mind Gobbler immediately broke the domination effect, and Xanphina's consciousness returned—though she remained trapped in the sphere, confused and demanding to know why she was in "this little ball."
"You were under the control of the giant turkey," Shade explained as they began their retreat. "It's for your protection as well as ours," Karma added apologetically.
Desperate Retreat to Ilyra's Study
With Xanphina safely contained in the force sphere and the Mind Gobbler's regeneration making victory impossible, the party made the call to retreat. Shade cast *Fog Cloud*, filling the cavern with thick, obscuring mist that broke line of sight with the Mind Gobbler. The party grabbed the lightweight sphere containing Xanphina and fled, rolling the "hamster ball" ahead of them as they sprinted through the tunnels.
Behind them, they heard the Mind Gobbler shrieking in fury, its gobbles mixing with psionic screams that echoed through the cavern. Its psychic presence hammered at their minds even as they fled, but the fog cloud broke line of sight long enough for them to reach the tunnel. The gobble thralls pursued, tentacles scraping against stone as they gave chase, but the party's speed advantage let them pull ahead.
They raced through the darkness, Alexios now carrying the unconscious Keyleth, while others took turns pushing or carrying the force sphere containing Xanphina. The Mind Gobbler's psychic gobbles echoed through the tunnels behind them, growing fainter as they put distance between themselves and the creature.
As they reached the area where the domination's range limit broke, Xanphina's wits fully returned to her inside the sphere. "What happened?" she demanded, still trapped inside the shimmering ball. "Why am I in this little ball?" The party explained as they continued their retreat, promising to release her once they reached safety.
Alexios used his *Jaunty Boots* to teleport back and retrieve his valuable *Psychic Disruption Knife* that had been lodged in the Mind Gobbler, not wanting to lose the weapon. He then teleported back to the front of the fleeing party.
The party didn't stop running until they reached Ilyra's study. They pounded on the magically warded door, and it melted away to reveal the drow researcher. "Come in, come in!" she called, gesturing them inside urgently. Once everyone was through—including the force sphere containing Xanphina, which DM Wes humorously "accidentally deleted" from the digital map to represent releasing her from the sphere—the door reformed behind them. The magical ward sealed completely, and they could feel the oppressive psychic presence of the Mind Gobbler disappear, blocked by Ilyra's powerful protective magic.
The Experiment Revealed
Safe within Ilyra's study, battered and exhausted, the party collapsed. Keyleth regained consciousness, stabilized by Karma's healing magic. But as they caught their breath, Ilyra's first words made them realize something disturbing about their harrowing battle.
"That was quite the display," Ilyra said with academic interest. "You made it much further against the Mind Gobbler than the previous party did."
The party froze. "The previous party?" Xanphina asked, her voice dangerous.
Ilyra continued, oblivious to their growing anger: "So, what did it feel like when it was unleashing its psychic energy on you? And please, as many details as possible—these observations are key to understanding this creature."
"What the hell?" Xanphina exclaimed. Gootcha demanded, "You couldn't tell us about the fact that it turns into a bigger one?"
"That is actually new," Ilyra admitted. "We had not witnessed that phenomenon before."
"Or about the fact that we were your research?" Xanphina accused. "That's kind of shitty, man."
Ilyra seemed genuinely confused by their anger. "I thought I was pretty clear that I was researching the creatures in this cave system. I thought it was obvious that going to fight the Mind Gobbler was part of the observations."
Then Karma revealed the most damning detail: "We saw you watching with a mind flayer. What is the story there?"
Ilyra explained without hesitation: "Oh, of course! The Mind Flayers are also curious about how this creature was created. It appears that soon after its creation was complete, it immediately destroyed and consumed the brains of all the other Mind Flayers around it. So the Mind Flayers in the area would like to better understand how this creature has become so powerful."
The truth was clear: Ilyra had been observing the party's battle from a safe distance alongside an Illithid observer, both watching as the party risked their lives against the Mind Gobbler. It was an experiment—adventurers sent to fight a dangerous aberration while researchers watched and took notes. The party had been lab rats, and they'd nearly died for Ilyra's research.
Some party members acknowledged that Ilyra had technically been clear about researching the creatures, and she had given them the knife as a tool. Patty noted, "If she puts it like that, she kinda did warn us." Alexios admitted, "I don't think she's technically wrong, but I'm still pissed, and the rats are mad as hell."
Ilyra apologized if she hadn't properly prepared them, but maintained that her intentions weren't malicious. She even suggested that if they would go back and fight the Mind Gobbler again, it would be valuable to see if the creature had learned new abilities from their encounter—because she believed it could adapt and learn from the magic used against it, much as it had learned from her own spells in the past.
The party unanimously declined. "I don't think we're really interested in fighting it again," Karma said firmly. "We barely made it out of that one."
Ilyra offered them sanctuary for a long rest in her study, promising the wards would keep them absolutely safe. She also offered to create a *Scroll of Featherfall* for them while they rested, which would help them navigate the great chasm. The party, too exhausted to continue and needing the safety of the warded room, reluctantly accepted. They settled in for a long rest, knowing they would need to find another way out of these tunnels—one that didn't involve going past the Mind Gobbler again. Before sleeping, they asked Ilyra about alternate routes, and she mentioned the deep gnomes (svirfneblin) who lived somewhere in this tunnel network and were masters of stonework—they might be able to help create a new exit.
The session ended with the party resting in Ilyra's study, alive but humbled by their encounter with the Mind Gobbler, and newly aware that they had been observed and studied like specimens in an experiment. The Mind Gobbler remained in the depths, a threat yet to be overcome—and now it had learned from their tactics, making any future confrontation even more dangerous.
