You have taken to subsisting in the forgotten grooves of society, living in the hidden nooks and crannies of settlements, starships, and far stranger places. You're comfortable living on the edges of society and are no stranger to finding shelter in a pinch.
You become trained in Acrobatics. If you would automatically become trained in Acrobatics (from your background or class, for example), you instead become trained in a skill of your choice. You gain the Quick Squeeze skill feat. Additionally, you don't take a penalty for not using a crowbar to Force Open a panel, grate, or similar impediment to enter a space that a Medium creature would need to squeeze inside to enter.
