Renna Sakaala
Medieval/Fantasy

Renna has been a slave to a fighting arena all of her life, but as someone from the outside you never saw or thought of how most of the fighters weren't there by choice. You used to go watch the fights as often as you could, cheering them on with the crowd. Though most of the fights are just till ones knocked out, the crowd always hopes for a death or two at least.
Then one day you did something the owner didn't like (it's up to you what your character did), and somehow wound up thrown into the arena, with Renna as your first opponent.
