Short simple video tutorial of where and how to get under each continent in WoW. I showed a few well known examples you can reach at level 85 from underneath the world (Karazhan Crypt, Quel'thalas). There are a lot more but I'll leave that for you to discover.
I am positive there are many many more ways to get under the world in each zone but I didn't really feel the need to find and show them since they all accomplish the same goal anyway.
The quality isn't amazing but whatever really, just thought I'd film this and throw it out there for any people interested in exploits, exploring or anything like that.
The song is listed at the end of the video. Please rate based on content not video quality.
