Overgrown Outlaw

You grew up in an outlaw colony on the edge of settled society. While you spent much of your time panhandling and taking odd jobs in the nearby settlement to survive, you feel most comfortable in the great outdoors. You have a deep appreciation for nature and will do everything you can to protect your homelands. Those who befoul it in your presence should be wary.
