Originally she is from Rohan, but she just lived there, permanently, when she was a kid. Now she is a huntress and a guide, that is why her accent is not entirely rohirric, you can notice it just if you are a good listener. Her accent varies, sounds like a mixture of different areas in Rohan and some places of Middle Earth.
 Later in life, she followed her two sisters in their work but when her sisters abandoned the job, she continued with it. Her work is to guide people who hire her, among the woods or other type of landscape. She has survival skills that help with that becouse many times her path in the land is dangerous. So, she will drive them safetly to the place they need to go, but mainly in Rohan.
