Tó Bájíshchíní was born of a white man and a Native American woman. She resented her father for making her mixed race, as it caused her to never feel part of either world. At some point she was turned into a vampire, making her finally feel like she belonged.
Tó killed both her father and the Watcher of Slayer Naayéé'neizgháni, for which Naayéé'neizgháni hunted her down. The two fought, and Tó was staked by Naayéé'neizgháni, but not before Tó mortally wounded the Slayer with a knife.
