Zariel’s fallen companions cannot rest. Nobody can in this nightmare hellscape.
— The Cartographer

The onyx steps descend into catacombs containing the remains of Hellriders who died fighting at Zariel’s side. Their restless spirits yearn for peace yet are doomed to haunt this place until once more called to arms.

Dozens of dead knights kneel before the monoliths, their foreheads resting on the pommels of their swords. The knights’ armor serves as caskets for their bones, yet their corpses stay upright as though in prayer. Each knight wears the faded regalia of Elturel.
