Okoyo doesn’t talk about her childhood. She lost her family to slavers, and when they came for her, she fought hoping for a quick death.
Only to be saved by Ababuo, who attacked the slavers killing them all.
She traveled for a few years with Ababuo, learning about Vampires, the Medjai, and how to fight. In time she asked Ababuo to Turn her and be trained as a warrior.
