The dispossessed
People you would think have nothing left. What somebody has doesn't have to be expensive or valuable financially to be held sacred by a person or group you're trying to take something from, even if most things taken tend to be out of financial interest rather than for any other reason. It is the belief of some that if you take that which someone or a group of people holds most dear, you've taken everything, you've taken what they're made of. It's like walking up behind someone and stabbing them in the heart, or between the ribs.
He/she would live off the land of the dispossessed, make what was theirs his/hers, try to make their lives his/hers, might even try to become him/her/them. The desperate ones who tried to dispossess the others had always been imitating somebody else, they knew how to imitate for a living, they were good at it.
