This is what I have for Inana so far. I can't think of anything else at the moment, but it's a start at least.
Inana considers herself a true child of the woods. As a baby, she was found and taken in by an enclave of Elven Druids who raised her as one of their own. It was a happy childhood, until a band of brigands came and slaughtered everyone. One was about to kill her, when she felt the presence of another being. Calling itself the Spirit of the Forest, it fused with the young Gnome, turning her into a killing machine of woodland vengeance. Since then, she has dedicated her life to protecting the forests from those that would corrupt it.
Inana doesn’t like interacting with other beings if she can help it, although, she is more likely to open up to an Elf, if anyone. She has a very deep reverence for the woods, and grows furious against those that cause harm to it, outside that necessary for survival or course. To those she perceives as a threat to nature, she will attack with full fury, and not stop until they either flee or she kills them. She mostly is able to accomplish this on her own, but if the task gets to be too much for her, Inana will call upon the Spirit of the Forest to aid her.
