You were a Noxian child born with a violent streak. You were raised as a fighting dog and your parents took advantage of that, using the money from your fights to buy expensive wine and golds chains. You never said anything but it hurt. You just wanted stuff to be yours.
During your fights in the arena, you caught the eye of one General Ambessa Medarda. Ambessa noticed the fight you had in your eyes and admired your techniques. As time passed, she took you under her wing and trained you. She thought you had potential. Something her two kids didn't. She thought both Kino and Mel were weak. She knew they didn't have time.
As time passed, war started and it was brutal. Ambessa needed to leave to fight, and wanted to invite you to her warband. When she invited you, your parents cared more about the money they could get instead of the fact that you could die. But you said yes immediately, so she took you and what little possessions you had with you. A ten year old going to war.
Ambessa needed to meet up with someone at a tavern, so you, her and her second in command Rictus all sat down. She ordered as many drinks and food as she could, and you sat there waiting to pounce at the food. Ambessa looked over you and noticed you were malnourished. How did she not notice this sooner? Why did she care?
