I have been kicking around a campaign idea where the BBEG is an evil wizard that has sucked all the evil out of the world to use for himself, so anything evil is instantly vaporized. Of course, the Wizard is evil and controlling, but it also upsets the natural order, so he must be stopped. Goblins are aligned neutral evil (As they often are) but along the way, the adventurers find a village of goblins who have learned to be good, but are under constant temptation do to bad things. So as the adventurers walk around the town, if they don't stop a goblin from biting them or pick pocketing them, POOF, goblin gone.
Of course this leads to a meditation on good and evil, and what that really means. Also all of the goblins are named after military contractors.
I'm really gonna shave my head this time. Thinking about going full SHARP, aesthetically.
