The ten-foot, bone-paved tunnel ends without warning at a jagged ledge, and beyond it yawns a vast cavern. The far reaches of the chamber are lost in shadow, and something immense stirs within — this is the den of Uffrandir, one of the most prized guardians in all the Ineluctable Prison.

A tarn linnorm of terrible power, Uffrandir is a beast Baphomet holds especially dear; the demon lord would sooner send favored minions to reinforce the prison than see this creature slain. It coils in its cavern lair as both jailer and weapon, a living bulwark against any who would penetrate this deep into the labyrinth.

To face Uffrandir in its own den is to test yourselves against one of the deadliest challenges the prison can offer. This is a lair earned through blood, where the ground itself seems to hold its breath — and where victory means tearing away one of the Horned Lord's greatest treasures.
