Baron Blemish

Born a half-blooded scion of the royal house of Diamond on the world of Luster, young Blemish spent his youth honing his incredible combat skills in service to his house while quietly seething that his father’s indiscretion could forever bar him from ruling, rather than merely serving. Even the manifestation of royal magic— his impressive darkstone generation, with creates diamond-hard, inky-black crystals—was not enough to convince his cousin the king to show him the respect due a noble. He refused to acknowledge that his own greed and temper often sabotaged his opportunities to earn that respect, rather than any outmoded social customs.
Eventually, Blemish opted to seize power himself rather than beg for it, staging a coup and putting most of House Diamond to the blade. Only young princess Claire escaped the purge, returning years later to lead a pathetic rebellion against his power. But once again, the royals of House Diamond ruined Blemish’s bid for rule; The war destroyed Luster and cast its population across 10,000 worlds.
