12.2 MUST be Azurmist / Bloodmist Isles (spoilers in post)

The draenie are the mirror to the belves. The draenie heritage quest teased a brand new city being built.

What better time than midnight to introduce it.

As for story beats, Turalyon is being set up as a problem in Mid and the dude has the Vindecaar parked in Azurmist, so that's a reason for us to go there.

Maybe he snaps and wants to use the Vindecaar in a dangerous way, like how we kill Lorthraxion, and we have to stop him.
