Fights with a Horde

You were once part of a much larger martial society, where you held a position of elevated respect. The society might have been a tribe of abhumans, a military unit, a secret group of warriors that live in a limited dimension, or something else. Whatever the specifics (which you and your GM should work together to decide), you formed close personal ties with them and trained to fight in small and large groups alike. But at some point, you left, perhaps to seek your destiny, because you were exiled, or because everyone in the society spends a significant time away before returning to retire. Though you are gone, the lessons of teamwork and leadership that you learned while part of that society remain with you.

Whatever you wear, it likely includes the symbol, insignia, or some other reminder of the group you left behind.
