Paco and Tina grew up knowing nothing about their family. Their parents passed away when they were little, and their grandparents refused to give out any substantial details on who their parents were. Things didn't start to make sense until their grandmother abruptly revealed that she was scheduled to die, and that their familial history had everything to do with it. They soon learned after that their fates were spiritually intertwined with the long thought to be extinct dragons, along with the serpent-like monsters their ancestors had supposedly defeated centuries before.
