[@Venku] Hmm, not so sure. A domain is meant to be broad, but I think Unity/Division are bit too ambiguous. Rather than Division, I would have used something more like Discord, Conflict (in fact, I'd say these are more Portfolios than Domains, (Discord) can come under Chaos, War; (Conflict) can come under War.) Things like War, Trickery, Chaos etc. are more Domains than Portfolios, so I can't see them coming under Division. If you do want something like Unity, I would suggest you have it as a Portfolio and perhaps choose another word, maybe (Harmony) or (Balance) and have a wider Domain, something like Law, Order or anything else more fitting.

I did actually think of fission/fusion, but even those I wouldn't put under Division/Unity. They're more related to Science (Atoms) which is Evelynn's Domain (Portfolio).

It's just that Unity as a Domain seems really ambiguous and so does Division. They can potentially apply to anything and everything within any other Domain. Your character is interesting overall, it's just this tiny thing that just doesn't sit quite right with me. Sorry if I come across as pedantic, but there we go.
