Half of Oberon's powers came from a powerful alien race(I'll find a name for the race later X'D). When he was born, he suddenly had a heart failure and only had hours to live. Desperate to save his newborn son, King Darkus used his power to contact the King of the alien race and begged him to share his power with Oberon to save his life. The alien king agreed and gave some of his power to the newborn baby, but on one condition, when Oberon grows up into a young adult, he will become his servant for eternity. After the king left, Darkus didn't want his son to become a servant when he grew up, so he shared some of his own dark magic with Oberon, along with a spell that wouldn't allow the alien king to track him down and take him.
