The upper part of the level is where the main part of the cathedral is located. Distinguished by its Gothic-style achitecture, it features five altars and shrines dedicated to each member of The Five. Each altar also includes a corpse of that respective member.
On the initial visit, only 2 of the conduits are open. The other three have to be opened via retractors. 2 Dark Souls can be found here. There is also a large hole in the central area (PC, Dreamcast and Remastered versions only) that leads to the lower area. A small theatre-like area can also be found on the upper floor (PC, Dreamcast and Remastered versions only).
This area, along with the rest of the Asylum, was destroyed upon Legion's defeat at the hands of Shadow Man.
