I guess I would be a new recruit. I am an artist, photographer, graphic designer, web designer, videographer, and 3D modeler... however, I currently have two part time jobs and go to college to do all I just listed professionally one day. I am also a stunt performer with a local jousting group, and a charity costumer.
Lets just say this character in the group would be like a little girl who heard about Matrim in the Wheel of Time universe, and some how started to idolize him, after he helped save her village. She grew up secretly learning weapons, and steadied war tactics. She became a guards men, lets say similarity to how Mulan secretly enrolled in an army. My other idea is that she is alternate version of Mat like Gwen in Intro the Spider Verse, but I like the idea of her being someone different but grew up kind of like him. I am sure Nynaeve would box Mat ears for being a such an influence on little girl, and he'd have some retort about not wanting to be a bloody hero, not his fault, etc.
