Goyar ak Ryush, hero of ancient Illustria and the war against a'Rasyr (I changed the spelling since this drawing from 2012/13) The tattoos are enchantments that arm him with the sword and give him invisible armor

photo of a pencil drawing in an oversized sketchbook. a beautiful and heroicly nude man stands tall, a long bladed spear in his left hand and a khopesh in his right. his muscular body is covered in tattoos of whorls and swirls. Over his left arm is draped a banner with three round sigils on it: a unicursal hexigram, a divided circle, and a stylized flower. text to the side identifies him as "Goyar ak Ryush, Black Knight of Illustria and Hero of the Raisyri[sic] War" and goes on to describe him as, "Not the greatest tactition of the war against a'Raisyr(sic) but a warrior of legendary prowess, Goyar is most famous for wading into battle wearing nothign but his magically bonded armor and a flag bearing the marks of his god and his house."
