Emalon the Storm Watcher 25 man - 3.1.0 PTR
This is the new PvP boss in Lake Wintergrasp.
Seems like this is going to be almost as easy as Archavon is today.
They share the same raid instance, but are separated in two different wings.
Emalon resides in Hall of Repose(?)
Video is from a kill on Brill PTR.
Loot included in the end.
