Zul'Gurub inside Karazhan - Out Of Bounds Exploration & Development History
Explaining how to get out of bounds in Karazhan (the original version) and visiting a part of Zul'Gurub during it's development cycle.
This was performed on a "Wrath of the Lich King" private server, but was at least possible until Mists of Pandaria on the official servers, probably even longer.
As a bonus: other areas outside the raid instance are explored as well and some juicy trivia about the Classic development gets elaborated on.
Hop in and enjoy scenes you might have not encountered yet.
