Iron Heart

From PathfinderWiki

The Iron Heart is the very centre of the infernal city of Dis, the vast metropolis that makes up Hell's second layer. All roads in Dis lead to the Iron Heart but only the highest ranking devils, Dispater's court and advisors, and those granted special leave are allowed access to it. The Iron Heart itself is made up of a darkly magnificent array of palaces, pleasure gardens and burning monuments to the glory of Hell.1
