Thanks for the response.

Although I am certainly curious what does happen when you remove darkness. I mean, what else could there be? Nothing is, by definition, darkness, so can darkness users just drain power from a room infinitely?

The problem is that that's sharing power. It's one Aedis giving power to a different Aedis. Using their power to create something the other Aedis can drain. I was thinking of the very act of draining creating something the other can drain. Which would allow for an infinite loop, both Aedis gaining power, as opposed to one Aedis giving power to the other.
