Hey [@Fairess], so sorry I haven’t been able to respond earlier. Everything is great so far, thank you for being so cooperative. I’ll just give you a brief summary so you can continue with things; sorry I can’t help you as much as I’d like. 

Point 2
If she’s able to spot ill intent (directed towards her charge mostly), that should be a good enough way around it, right?

Point 3, I still have to give some more thought about. Might be as late as mid-next week I’m afraid, I’m super busy right now.

Everything else is okay and as far as the Great War is considered, don’t worry, that was over 3000 years ago. I like the idea of her being an ex-Council member which would be another possible link with Toki because she’s been raised by the last surviving Archangel (among others). For that sake she doesn’t need to be raised in Heaven, they could have just met on occasion or even more recently when Toki came to earth. In fact, your character could have helped with that. 

Also don’t be afraid to consider other link with other characters, we’re all very friendly and willing to help.
