Lead by Wrathion for Alliance and Ebonhorn for Horde.
Racial ability could be a flight form akin to druid's, in the form of a black dragon.
Model could use the human model, appearance options would be limited to variations of dark skin akin to Wrathion. Red eyes, claws on hands.
Heritage armor could be like Wrathion's where it looks Egyptian-inspired.
This would be the coolest thing. Blizzard please.
Note: Wrathion was in the Alliance embassy in the Blizzcon 2017 demo but then removed.
