Sett is the Boss of the Navori fighting pits: a half-vastayan, half-human brawler who rose from poverty, rejection, and public violence to become one of Ionia’s most powerful underground figures.

Born to an Ionian vastayan mother and a Noxian human father, Sett was rejected almost from birth. His mother’s vastayan community saw his mixed heritage as a violation of tradition, while humans treated him as a dangerous outsider. His father, a Noxian pit fighter, eventually abandoned the family, leaving Sett and his mother to survive alone.
