Honestly? I was sort of expecting demons. Don't know why. But it's vague enough that it could be, like Rawk said, a genetic experiment fuckup. Or, more likely perhaps, another person with powers whose powers either didn't manifest correctly or had terrible side effects. Remember, demonic can be used to describe something that isn't necessarily a demon. 
Personally, I'm guessing this thing is a failed super power person who's attracted to the large concentration of powered people, sort of like an AIM ghost in Raildex. I'll be interested to find out the actual explanation though.

To be fair, the whole premise of the RP is supernatural. Super powers and all.

Okay, yeah, I'm going to be dropping out of this RP immediately. Thanks for the fun times but this is just a little bit too much. I believe Biscuits is joining me on this one, we're both leaving.
