The Martian Emperor and Princess Asseylum's grandfather. He founded the empire in 1972 when the Aldnoah technology recognized him as its master, burning its activation processes into his very genes, giving him supreme authority over them. All of his descendants share this power, and he can grant limited control of the Aldnoah's powers to others. Utilizing this power monopoly, he based the authority of his empire on this military force and created a class of warlords loyal to him who would become the Martian Knights. He retired in 1997 due to health problems, but when his son and heir, Gilzeria, was killed in the war of 1999, he was forced to return to the throne.
