Time for a Big Bad, so meet Oro:
Not much is known (or least, I’m not willing to share, yet) about Oro other than he is from an alternate dimension and has vast power. He has involved himself in the affairs of both Sumina and Earth Realm over the years, possibly centuries. Oro is as evil as evil gets and played a part in Earth Realm’s invasion of Sumina. Also, he bestowed the Scarred One with some of his power.
FYI, the symbol Oro wears is a clue to his origins and reveals a link to a previously created character. Of course, that’s not the only clue…Hmmm.
