I'm not entirely sure! Usually my character starts taking shape when I make them in character creation. I keep trying to get a handle on my first Hawke, but she keeps eluding me

Not having an Origin does suck for this. A lot of what "inspired" my best Wardens' personalities was something in their Origin. My city elf being scared of her own shadow and always trying to avoid conflict was because she'd learned not to fight things stronger than her in the alienage, for example. I can't really get a HOOK on Hawke to start building a personality for her ...
It's actually driving me crazy how I can't get a solid idea in my head, dammit, because I really don't know HOW she'll interact with Fenris. I don't even know if I'm going friendship or rivalry, yet, bah!
