Walter Mercy Backstory

Walter Nathaniel Mercy was born on the plains. His Grandad came to the plains alongside his family about 10 years before the rebellion started, including Walter's own father who was just a boy at the time. He was a doctor and made a respectable sum treating the people of the plains, although he always had a fondness for the local tribes and cut them deals when he could afford it, usually trading his services for local herbs and food. During these visits his son became friends with a girl in one of the tribes, and as these things are want to do, blossomed into something more. After a bit of convincing from his father the tribe agreed to allow him to marry her, even giving him and his father a more or less honorary spot in the tribe. Finally about 15 years after his Grandfather settled on the plains, Walter was born. He grew up learning the art of medicine from his grandfather, learning how to shoot from his father, and learning to care for nature and the beings that call it home from his mother. He hunted with his family on his mother's side on occasion, although he never was one to hurt animals if he could help it. During one of these hunts, they came across a Margay Cat den after killing the pair living in it. It was here they found a small kitten that Walter insisted on taking with him, something his father was not happy about but with a little nudging from his mother he was allowed to keep it. As it grew his mother showed him special herbs he could feed it to make sure it would grow strong with him and be able to protect him always.
	Of course this happy life could only go on for long unfortunately. One day when Walter was only about 21, his Grandpa took in a stranger who was suffering from a strange bullet wound that seemed frozen around the edges. Not quite having to materials needed to treat both a gunshot wound and frostbite, he sent Walter to the tribe to get what he needed. He came back the next day to find smoke rising from his family's house, not quite having engulfed everything yet. He rushed in, trying to find anyone he could, and was only able to find his father before the fire and smoke got too bad. He pulled him out of the house and managed to rouse him to some semblance of consciousness to ask him questions. The man they had taken in was being chased by someone. A man with a blue bandanna and a silver gun that shot much more than bullets. He channeled magic itself through the gun and set the house ablaze after scorching his quarry and shooting his grandfather when he tried to stop him. Walter tried to ask more, get something more out of his father but... the smoke was too much for him. So, with the gun his father gave him, the cat his mother helped him care for, and the medical skills his grandfather taught him, he knew his mission. To find the magical son a bitch that did this and put a bullet in his head, helping as many people as he could along the way. Somewhere between then and now, took his last name as a title and started calling him Doc Mercy.
