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.

Desperate Retreat

As the situation grew dire, the party realized they could not win this battle. Alexios was grappled by three thralls simultaneously, unable to break free despite his considerable strength. Xanphina was bloodied and burning through her rage, her ancestral spirits flickering as her stamina waned. Karma had exhausted most of her spell slots keeping people alive, and Keyleth lay unconscious once more, unable to continue fighting.

Shade made the critical call: "We need to go\! Now\!"

She cast *Fog Cloud*, filling the cavern with thick, obscuring mist that broke line of sight with the Mind Gobbler. Xanphina broke the grapples on Alexios with a mighty blow of her flail, shattering thrall limbs and freeing the paladin. Karma grabbed the unconscious Keyleth and wild shaped into a giant spider, her eight legs carrying her up the cavern wall with the ranger secured on her back.

Gootcha used her Cunning Action to disengage and sprinted for the exit, her rogue training allowing her to slip past grasping tentacles. Alexios pulled back, shield raised to cover the retreat as thralls lunged at him from the fog. Shade cast *Expeditious Retreat* on herself, using her bonus action to dash away while maintaining the fog cloud with fierce concentration, knowing that if it dropped the Mind Gobbler would have a clear shot at their fleeing backs.

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 still-unconscious Keyleth, Xanphina guarding the rear with Garmok's Flail ready to strike any thrall that got too close. The Mind Gobbler's psychic gobbles echoed through the tunnels behind them, growing fainter as they put distance between themselves and the creature. It was not dead—merely left behind in its lair, victorious in driving off the intruders.

The party didn't stop running until they reached the relative safety of the upper levels of Garmok's Mine, finally collapsing in the dwarven corridors where worked stone replaced natural cave. Keyleth regained consciousness, stabilized by Karma's healing magic. They took stock of their situation: battered, exhausted, spell slots depleted, but alive. The Mind Gobbler had survived their assault and remained in the depths, a threat yet to be overcome. The session ended with the party recovering from their harrowing encounter, knowing they would need better preparation, new tactics, and perhaps the courage to use Ilyra's knife more effectively if they were to have any chance of defeating the aberration in a future confrontation.
