Cathedral of the Forsaken

The Cathedral of the Forsaken is a Site of Grace in a catacomb prayer room deep in the Subterranean Shunning-Grounds, far beneath Leyndell, Royal Capital. Simple pews face an altar flanked by skeletal statues holding a ghostflame censer, and clumps of bodies hang from roots creeping down from the ceiling. Cosy it is not.

This room is the arena for Mohg, the Omen. Beat him for the Bloodflame Talons incantation.

Behind the altar is an illusory wall leading further down to the Frenzied Flame Proscription. The way stays sealed until you have defeated Morgott, the Omen King.
