[@Rai]  Okay, so here's my concept.

The woman is a hunter/trapper of a rather powerful and sophisticated tribe.  They use riding animals to scale the mountain peaks and she uses a rifle to hunt.  I would like to use the rifle as a form of casting magic, I have some ideas for her.  Her mount would actually attack with her, but would be so big it wouldn't be practical for anything indoors.  

EDIT- the Rifle would be a one and done on most battles unless she gets some time to reload.  She'd switch to a sword and board style after that.
