Info Zealot:
Zealot's real name is Lady Zannah of Khera. Born on the planet of Khera, Zannah and her daughter Kenesha (who at the time believed Zealot was actually her sister) were stranded on Earth thousands of years ago when their Explorer ship crashlanded after a battle with a Daemonite warship. Zealot just survived thanks to her lover, Stratos, who put her in an escape pod. Zannah and the other survivors were scattered, forced to hide themselves amongst the human population. Their enemies had likewise been forced down, and though less humanoid, the Daemonites used their powers of possession and shapeshifting to blend in, too. For the next few millennia, a secret war raged, with the Kherubim defending the vulnerable and oblivious humans from their would-be conquerors.
