Nara was born to a wandering tribe, and spent his early years roaming through forests and grasslands. He grew up learning to fight, hunt, sneak, and watch everything. Unfortunately, his tribe wandered into a region claimed by giants. Nara ran as his tribe was killed in the ensuing battle. Alone, he only had himself to rely on for a few years until he found a city.
Struggling to survive in an environment he wasn't used to, a group of petty thieves (recognizing his potential as an enforcer) started taking care of him and teaching him how they did business. Over the next few years Nara learned quite a bit, but unfortunately times were lean... as the group got more desperate, they started robbing people they previously wouldn't have bothered with.
It didn't sit right with Nara, and the final straw was when they tried to rob an elderly man who fought back, and the thieves ended up killing him. That night, Nara killed the small group of thieves and set out into the wilds, alone again.
