Well, obviously they broke the oath because I'm 16 right now, I was suppose to be claimed three years ago. The effect of the broken oath was what you guys call them, Zarkon's Army. Hecate, the Goddess of Magic, sent us here on a quest to defeat the alien guy. But apparently, she wanted us to run into you guys, the Paladins of Voltron, for help." Ava explained.
