Mostly a mystery is this boy's background. He keeps his past to himself most of the time. His mother died when he was at a young age. Before he knew it, he was alone and on the streets of Bree-town. Not the safest place to be for a young child. Years after this even, Tim ended up meeting a woman named Rinni and a man named Guvadan. Thus his life changed. He traveled on a trip to find treasure with a few other folk, resulting in his possession of plenty of coin. Since then, he's been on different expeditions, each giving him more coin. After recently being imprisoned for a good while, Tim is completely different. So, don't expect the sly, sarcastic, and coin-grabbing boy that he once was. 

As of recently Tim seems to have returned after a long leave of absence.
