I'm hoping for that kind of game! One of the players tends to lets his wish fulfillment get a little out of hand when he plays, but he's a good guy outside of gaming and I'd feel bad not inviting him. :/ Judging by how he's played "evil" characters in Pathfinder, I can see him getting out of hand quickly.
I put "evil" in quotes as I know that the Tyrants and most of the Neverborn fit the descriptions of evil, but I wanted to put in a custom Tyrant that is neither good nor evil and call it Legacy. Legacy takes the form of a giant carnivorous book whenever it is summoned and its goal is to make sure that Malifaux lives on, no matter what the cost may be. This means occasionally be proactive and foiling the plots of the Resurrectionists, Arcanists, and others, though at the same time hammering down on those that try to change Malifaux to be different than it always was.
