Prophet of Sseratus is one seriously awesome looking snake. You have to slaughter him for the quest Muddled Prophet of Sseratus.
For the quest Dark Horizon you have just been turned into a scourge and
Gorebag flies you around on a tour of Zul’Drak. I loved being a scourge.
For the quest Fuel for the Fire you control an Abomination and kill 60 Drakkari Skullcrushers and lure out 3 Drakkari Chieftains. It was a lot of fun!
This very cool gargoyle and equally impressive Blightblood Troll were in some temple we had a bunch of quest to do in which involved Drakuru.
