The Ride of the Hellriders
The Ride of the Hellriders — in 1354 DR, the paladins of Elturel opened a gate into Hell and rode through it.
Devils sought to take the city. Rather than wait for the assault, Elturel's paladin corps opened a portal beside their fort, the Gray Watch — now Nuts Deep — and rode into the first layer of Hell, to fight the devils back on their own ground. They won, at terrible cost: the gate closed behind them, and only a handful ever found their way back, by various means.
Elturel's paladin corps still bears the Hellriders' name. Today's paladins are not those who rode, but they keep the pact: no devil shall hold influence in Elturel. The portal's residue made the Gray Watch uninhabitable for long stretches; the residual energies have long since dispersed, and no infernal energy lingers at the site today — though Deez Nuts now garrison the doorstep of a former hellmouth.
The history was told to the party by Marshal Ulder Ravengard (S52) and a Dawnbringers Banneret (S53).
