I do this for survival.

Ah, yes. You were kicked out of the house at the age of sixteen. Your parents couldn't afford you so they decided that leaving you for dead in the middle of the forest would be best to stay out of trouble. What they didn't account for was that you found equipment from an old abandoned campsite.

You were able to fight and claw your way back to civilization where you learned that your parents never made it back to their home. Instead, the creatures of darkness, the Grimm, found them and killed them. Their fear made them targets. You couldn't inherit anything but the shack that they stayed in as they accumulated quite the debt. Collectirs came and took what they wanted, as the shack left no impression, they left it to you.
