The tomb on the Isle of Prisoners, once a castle for King Amraphenneset, is now a Dhorn prison. It can be reached through a hole in the floor of the prison, found beneath the old barracks. The tomb is a multilevel maze with a number of secret passages, countless traps, and hostile creatures aplenty. Some areas have been rebuilt by the Dhorn for their purposes and others sealed off due to varying hazards. An unarmed explorer could only survive with exceptional stealth and awareness. See History of the Isle of Prisoners for more information.
