Sweet Crom, Master of the Flying Guillotine has an incredible soundtrack. Neu! provides an awesome intro to the villain (who has mastered the art of the flying guillotine) with this song:
And really, the whole villain intro is just wonderful. The villain is entering the story because the hero, a one-armed boxer, has killed two men. These men were apprenticed to the imperial assassin, the flying guillotine wielder, and before their final fight, sent off a clay tablet bearing a drawing of their nemesis (the master is blind, so, gotta have tiny clay tablets). Have to love consequences of the PCs slaying folk, even if said folk deserved it.
HNNN that opening. The downside is that it's hard to describe some evil villain just straight-up coming to kill the PCs from afar, absent some prophesy, mushroom-tea hallucination, astral beast whispering, poison save vision, or near-death out-of-body experience. Which of course are things the game should be filled with, so, just keep them in mind for having some little 'cut to' part where the next villain is described, briefly but awesomely, practicing martial arts and burning down his own fucking house to come after the PCs.
