Hmm, which gives me another idea, if deities are involved. The Celestials have killed their own deity (somehow), and are using it's remains as a power source for everything they use. Bonus addition - Entropy. A dangerous and uncontrollable anomaly sometimes forming due to high concentration of said energy, like after a big battle. I would still need to figure out what Entropy would actually do.

Ideally, this would put up another contrast between Celestials and Humans/Elves/Demons - while others still have their gods, forgotten or worshipped, they have killed and exploited their own.

@Halvtand - check your PMs. I would like your opinion too.
