When Karazhan was first announced, there were rumors that an upside-down version of the tower existed, extending down from the bottom floor, deep underground. Whether or not Blizzard actually plans to implement this 'Lower Karazhan' remains unknown. It is likely that this is a reference to The Last Guardian by Jeff Grubb, a novel which details the last weeks of (living) activity within the tower. Several references are made to an "inverse" of Karazhan which begins at the lowest level and works its way downward, with Medivh's secret chambers lying at the very bottom. It is also possible that this rumour was a nod to the Konami game Castlevania: Symphony of the Night, wherein players could fight through an upside-down version of Dracula's Castle after completing the regular version. There exists a building behind the nearby graveyard in which there is a stair downward towards a locked gate. One could (and may still be able to) go through this gate as a ghost and explore the large area beyond. This is likely to play a part in the future of Karazhan. Karazhan could be based on The Dark Tower from the Stephen King novels Karazhan's basement could possibly be added in Wrath of the Lich King as an instance related to the Black Riders, or as the starting area for Death knights. There is also a door outside the Kitchen, in the area above the Stables. The door is locked and cannot be opened by any means. Looking into this room in a Map Viewer shows that it is an empty triangular room, about 10 yards in size. This also could be part of an extention to Karazhan.
