I like the idea of the Star Preacher. I always thought it was cool in the Star Wars EU stuff when folks hit on the idea of beings who manipulate the Force by a different name. I could see your Preachers in a similar vein...all one power source, even if it's veiled in the names of many religions.
I think Mr. Spahn said that the bounty hunter is going to be a part of the Companion. When will we get to see the Star Priest and Preacher?
