Editing Carceri (section)

===Agathys===
The final layer of Carceri is something of a curiosity. Consisting of only one sphere, a ball of black ice with red streaks.  Or according to some sources there are multiple spheres but they are too small and far apart to be visible.  It is lethally cold on the sphere and its petitioners are frozen in the ice up to their lips. The foremost landmark on this layer is the Necromanteion, the citadel of the death god [[Nerull]]. Here his priests perform necromantic rituals and experiments on hundreds of onyx altars in service of their dark lord, and houses many artifacts of the Reaper.
