I'm at work so don't have the books. They basically give you dragon-based abilities (mostly combat) like natural armor, energy resistance, a minor breath weapon, etc. I will almost certainly be using a prestige class from the same book (though I don't know which one) since taking straight sorcerer levels just HURTS.

I will work on the character tonight and post more info and questions then.
Since I don't know Greyhawk well, the character's background will be pretty generic but I'll try to make it at least somewhat interesting. As a sorcerer I'll have a big charisma and may end up taking the Leadership feat if that's OK with you (haven't decided yet). If I do that, do you want me to write up my cohort as well, or would you prefer to do it?
I'm really looking forward to this. Should be fun.
