The "evil leader doing good through pragmatism" is a fun angle and the setup reminds me a bit of Ari Marmell (Goblin Corps and the The Conqueror's Shadow are all about evil leaders actually not being that evil).

To clarify, are you looking for people to write the heroes that are being "used" (perhaps to varying degrees and knowledge on their part) by said bar maid? Or are you looking for players willing to focus on world building? Or both?
