Quentin Zero Moriarty, the last pureblood of the Moriarty Clan. If memory serves, the Moriarty's, Le Blac, and Von Stein clans along with the La Crox, Bloodfang, and Crawford's founded the Heart's Kingdom. Unlike the Bloodfang and Crawford Clans, who had inferior blood, those three clans could par the La Crox. However, instead of fighting for the throne, the three clans went on their separate ways to build their own kingdom.
Those kingdoms were now known as Karo Kingdom, Cross Kingdom, and Spade Kingdom. Just like the Heart's Kingdom, those three held the same power, and declaring war with any of them would result in unimaginable casualties for both sides.
But time had passed and the previous clan leaders had perished. The newer generations don't seem to think peace was always the perfect resolution. Whether it was their egos or greed for more power, Stefan and Zero from the Spade Kingdom seemed to share the same goal.
That was an Empire.
