Okay, let's see...

@edboy: Honestly, I think Supernatural is a bad basis for this, and you have to remember that it's unlikely any deities would have appeared in such a manner. Though there was ambient magic around. The major errors I see in your bio stem from the fact you're using Supernatural as a basis. This is nothing against anyone who likes the show, I just don't think it's a very good fit in terms of this RP's setting and mechanics.

@Tatsua: I less meant in terms of abilities and more in general power level. And honestly, reviewing your bio, I am very strongly against future-reading in any RP due to the inherent unpredictability of them. The most acceptable variation of it is much more like an extremely short-term sixth sense allowing the user to predict immediate attacks or the approach of danger.

Also, the OP is geared towards having the contracted beings be characters in their own right, which is difficult when there's so many limitations placed upon them that they can barely appear.
