How do you leave the tower in world of warcraft as a death knight?

Answer 1

first off, i dont even know how you got there if you dont know how to get back. But, what u need to do is go to the place that has all of the starter northrend quests, i forgot the name of it, then go to the dock, it will take you to SW P.S. (u cant leave acherus and eastern plaguelands area until you have completed the whole Death Kight 'chain' which ends you at lvl 58, so u cant even get to northrend at that lvl) GL

Answer 2

You do the quests in that first room then run over to the bird when you get the quest too and you can fly down
