The Darkening Wild
Basically the Beorning version of Brienne of Tarth.
Ennalda is a tall, strong shield-maiden living in the village near Beorn’s House. She is a fierce enemy of Goblins, Wargs and Spiders alike, and when Beorn is out roaming or fighting, people often come to her to resolve disputes. She is still rather young, having been left as a fosterling at Beorn’s House by he father as he went to seek his fortune in Dale. He never returned.
She is distrustful of adventurers, knowing that they can be irresponsible and violent, and she helps the village by keeping an eye on any who come by.
