I believe the ooc is finally complete. Goodness.
I finished the Aeon category and put together an estimated timeline - admittedly, I'm not terribly proficient at such a thing, but, it works. 

Anyways.
[@Prisk] - You create the Aeon that your character received cells from and in result the character gains the first stages of a limit break/overdrive that is in relation to the Aeon. Example being an Aeon of Red and Black that equals to darkness and fire.
So.
Red and Black - Fire & Darkness - fury and decay [or whichever nature that relates to the elements selected].
Thus the limit break/overdrive is a result of that, example of such could be an angry sort of decomposition that decays and rots enemies on impact like a burning acid or some such. Anything is plausible, and I'll be verifying it. 

[@Asgore] - Hah I can sympathize and relate. No rush though, others will be out for the holidays as well.
