It's not my authority to make you change, but you should be aware that Vestec already has the "chaos" domain, meaning anything Rtron chooses as a portfolio, you won't be able to and vice versa. If I were you, I wouldn't go for Chaos, so not to be limited by another.

You were talking about being in charge of death. That could fit into a lot of other categories. The first ones that comes to mind is 

"nature" (it's only natural to die), 

"balance" (life is balanced-out by death), 

"darkness" (death is always associated with darkness and badness, and that could allow you to have a lot of potential portfolios), 

"opposite" (death is the opposite of life. But, then again, imagine being the God of Opposite)

"order" (the guy who had order left, and death sorta keeps order to the universe), and so on. 

"evil" (I wouldn't call death evil, but some would), 

"destruction/decay" (that might be a portfolio, though)


Just my opinion on the matter, anyway.
