With the release of Patch 2.3, Blizzard brought us a new instance, Zul'Aman. As with the release of the Black Temple, Blizzard put together a trailer introducing the instance that gives us some background on exactly why Zul'jin is so very cranky these days.

Now I don't know about you, but I was personally a little confused as to why Zul'jin, a guy that's pretty much a god amongst trolls, would all of a sudden turn against the Horde. As it turns out, having to saw your own arm off will do that to a troll.
