Trokair thought I should share this find with the community. I do not know why exactly this happens, and I was hoping there is some way to use this. On August 1st, taumin, my glitching bud, and myself were exploring Old Hillsbrad Foothills with the Darkmoon Tiger. We were inside a Dwarven Fortress, right by the blue wall. We knew that if you darkmoon tiger past the blue wall, you will be teleported to the Northern Barrens, but my friend decided to do it anyways. When he was logged off, I happened to scroll over his portrait and it said he was in "Naxxramas". I quickly screenshotted it. At the advice of Trokair, we went back yesterday to record this. Please watch in the bottom left the location of Tyrrant the rogue. Couldn't stand no sound so I threw in a song.
