Glad to hear he went over so well. In regards to your points:
[list][*] I had figured he was initially weakened enough by the loss of Jegudiel that he was able to slink away, and after that he mostly just Invested away enough of his essence to remain personally only on the level of a particularly powerful angel. 
[*] As I understand it, Archangels are the original Created-by-God, lived-in-Heaven style Angels that possess the powers of all angelic types and have never been killed and reborn. Is that correct, or is there more?
[*] The Bio's been altered to reflect him running in general rather than running to Earth.

As for Rubra's ability, it's not tremendously important. I was just looking to give an ability to represent herself as a powerful Hellion in her own right counter to Alba (who's basically just a tank on two legs). I've altered her description to have her absorb and redirect magical attacks rather than fire off her own essence (I had just substituted the word aura for some reason, not sure why).

I imagine that he would have something of a nasty reputation among demons, yes. He wouldn't take pains to spread it, but I imagine word gets out that this guy here is Bad News if you don't want to end up as one of his flying monkeys. I can't imagine many demons appreciating being turned into a finger-puppet.

He would not, on the other hand, be of interested to the Peacekeepers. Jegudiel pretty much doesn't kill people. I mean, that would be wrong.

And wasteful. <3
