Nowhere near finished yet but I'm linking it here for now.

Hamza Dawnbright, the Lesser Aasimar Favoured Soul 6.

You mentioned that Forgotten Realms' variants of PHB races are allowed as long as they have no level adjustment and the Player's Guide to Faerun has the Lesser Aasimar so I hope that's okay. I'm also using an alternative class feature from PHB2 to replace the weapon feats Favoured Souls normally get with a temporary hit point buff for allies when I cast spells on them.
