I've been making assorted alts and cheerfully giving Elmetaph the wrong teleportation coordinates to see where they are going to end up when they teleport away. So, I'm actually pretty excited to read in the patch notes that there are now more possible destinations.
My grand favorite was landing on top of the giant fairy tree in Sun Vale - what a view! What a very long way to go down...
Edit: Teleportation coordinates can get periodically reshuffled. The Wiki has some known codes at http://wiki.projectgorgon.com/wiki/Teleportation but use with caution if there have been any recent zone changes since it may take a while for the Wiki to catch up.
