Here is going to be what Theramore looks like after Garrosh’s attack on it. Jaina apparently teleports her tower to Stormwind City. There is also a map of where in Stormwind her tower will be located.

Err, I don’t see her tower?

Isn’t that the Pandaren’s balloon? :/

That’s exactly what it is. It can’t be the tower because something is already there.
