Io

Io (named after one of Jupiter's moons) is stoic and no-nonsense. He was born into a peasant family and picked off the streets as a prisoner of war after said war ravaged his hometown. A nobleman took him in at a young age, gave him a name, and raised him to fight in the city's glamorous gladiatoral dome. The underground world of the dome lent itself to Io's nontraditional modifications, technically illegal by the city's standards but much enjoyed by the seedier purveyors and denizens of the dome. Io fights for guts and glory, knowing nothing beyond the lifestyle he currently holds. [Wow that's kind of depressing]
