We could do the wtich hunter thing. Stumbling upon a particular cult and following down the rabbit hole the uncover that this cult is impossibly, frighteningly powerful and deep in the empire. Go all over the Empire form capitol to small villages and hidden cult shrines and altars in deep caves and forests. The only downside I can think of would be the limited race palate. Humans, Maybe high elves or dwarves would care the most about the potential of the growing number of human cults. wood elves as rare, They wouldn't really give two shits about anyone or anything outside their forests.

But if we want to diversify and allow a greater option of races to play and enemies to fight, a Mercenary company is always an option. We don't have to be just in Kilsev though we can certainly be paid to go there for a while. But we can also travel and build a name for ourselves. 
I don't know. Personally I think I want a good witch hunter roleplay. that mood may change in time but for now. 

Last minute thought. We can be a troop of high elves scouting out a possible Druuchii Military invasion force or something. I don't know that idea needs refinement and is pretty half baked. I just thought it had potential.
