The following is a pictorial guide of some of the areas in the Karazhan Crypt.
The purpose or use of this crypt is completely unknown. There has been speculation that this is an early version of the "upside down Karazhan" area hinted at in the lore of the books, but the make-up of the zone and the content have virtually nothing in common. As such, we are left with just a very interesting hidden area with virtually no information about why it was created or what the original plan was.
Hidden behind a locked gate next to Karazhan in Deadwind Pass lies a large, horrifying crypt "dungeon" that few players have ever seen. While no one knows the purpose of this area, locations such as the "upside down sinners" room, with dead bodies floating upisde down on chains, make it one of the most intriguing lost areas in the game.
