First, I think I'll certainly explore the Mwangi Expanse. The mighty Ruthazek, the Gorilla King of Usaro, must be something to see. As he stole the experimental bombard of Alkenastre, he must have some purpose to it. And it would be thrilling to explore the old city of Jaha and the ruins of Kho, the ancient flying city. There must be some dark secrets there.
Then I'll probably go to Razmiran. A campaign about the fall of a false god must be something thrilling to experience.
