A few character suggestions, if you're still debating.
1 - While we have plenty of magic-users (Wizard/Sorcerer, and the both the Emissary of Power and the Focused Practitioner have Channeling), we are missing out on having Fae magic. A Faerie Knight (of an as-of-yet unnamed Court) would be a way.
2 - If you don't want the Emissary of Power's Template, the other option for a Scion is the Changeling Template. If you went with the Changeling-type option, here's what it would mean for you. The more power you accumulate, the closer to your supernatural parent you would become. So, basically, if you accumulated more power, you'd be more dragon-like.
