Alright, edited my post. To summarize my changes, other than balance changes (which you're free to add dice or something to as the situation demands, but I left that out of the CS) I added the bit about being found at one of Himlan's Temples of Myth (I'll PM you about the details a bit later when I collect my thoughts a little more on that.) I changed the demon around, but decided to keep her power the same as I had originally envisioned in my head, and added the scientific principle I based the power around in hopes that it would clarify things a little further. I also added clarity about the differences between her human food consumption and her demonic energy and mass consumption.

Lastly, I decided to take out the anime picture and add a short text description.

A lot of the nitty-gritty details are things I didn't put in the CS, for brevity's sake, and because they'd be expanded upon more in IC, so if you have any concerns about that, PM me or bring them up and I'll gladly clarify some more.

Edit: SirBeowulf, I wouldn't mind having a connection, but since a lot of Rose's time was spent in seclusion or entirely in the wilderness, I'm not sure how such a connection would have come about, especially with a more city-dweller type character like yours. Keep in mind that my character is a new recruit, so they wouldn't have known each other from the Night's Kiss in the past either. You may have to settle for getting to know each other ICly :p
