I'm basing my elf's personality and some of her looks on the awesome Billie Lurk from the game Dishonored: Knife of Dunwall. Billie is a lieutenant assassin working under Daud, the head of their black magic using assassin group. Her background is similar to being a First to the Keeper. I think her alignment will be lawful evil, She'll follow the traditions and rules of the clan but ultimately have her own selfish agenda like Billie. I plan on her being a mage with the necromancy spec.

Oooh Billie looks awesome.
I guess I'll make up an elf even if I probably won't play her.
She'd be a dreamer (not a dreamer dreamer just a normal dreamer) who keeps to herself a lot. Very somber and not all that eager for attention. She'd rather listen to a crowd of people arguing around her to get their side of the story then try to herd them into order. (Terrible leader material really). But her magical gifts are very highly prized among her clan. She's a peacekeeper and would rather guard and protect than attack and she favors staying as far away from human lands and as far away from contact with them (peaceful or hostile) as possible. Despite that she can't help but be interested in the cultures outside her own. I see her as very bird in a cage like but she's the one unwilling to step out.
She's not overly concerned about dalish heritage but she simply does it because it's expected of her and going against the flow is simply too bothersome and would result in too much attention on her. That said she does daydream about traversing the strange lands and cultures she's only seen from a distance at best. She just lacks the strength of will to leave the clan and explore and would rather avoid the confrontations she knows would result from that.
The keeper shoving her to spy and her getting caught up in the blast changes all that though 
That said I see her as one of my fail characters who screw things up constantly and probably end up dying near the end of the game if they don't go evil cause they're tired of being walked over.
