No. Villains will crop up as the antagonists in little mini-arcs, and since there are a lot of heroes, my impression is that SnS will contact you if she'd like you to write a temporary NPC Villain. She approached me to write the one that's going on at the same time as Ivy - presumably because she isn't comfortable writing males, and because writing Ivy AND every other villain that appears would be difficult - and he'll be there for a scene before disappearing for a while.<br/><br/>There are NO Villain PC's, just player-controlled NPC's.
