Level Range: 8-10
Deep beneath the thief tunnels lie the crypts of Tsunami, where the empty husks of long-forgotten players rot. A strange, unknown force in the area causes many of those empty corpses to rise and walk. It's said that the influence of some sinister, unnamed god plays a part in these violations; I don't know what causes it, personally, but I do know this: in the crypts of Tsunami, the dead do not rest. I visited the crypts when I was a young lad, around level 8-10, and tried to help lay those poor lost souls to rest. I recall that there is an entrance to the thief tunnels around Kyrse somewhere, and that the entrance to the crypts is very close to that.
