I am Space Jelly, Town Emboldener
My name is actually mentioned specifically as Geverid in the flavour but it says it doesn't make any difference because no one has heard of me anyway. My motivation for trying to stop the killing is that I want the town to worship me (:S). It mentions that the people in the town seem a bit weird, so I'm guessing that we're all pretending to be humans and each alien doesn't realise that everyone else is an alien.
As for my ability, well... I just used it.
I may claim as much as I want, including a full roleclaim. I'm basically vanilla and my ability is a joke reference to the post restrictions placed on the jellies in game 6.
I nominate CGMPW.
Heh, funny you should remind me of GhostQlyph right now of all times.
