Biography
Nina is the daughter of two Watchers, growing up in the grounds of the Watcher's Academy. At some point, Nina survived a mysterious house fire that left her lungs severely damaged. Her father eventually died protecting Buffy Summers — the Slayer who both caused hundreds of Slayers to be activated, and the end of magic which cut the Slayer line.
