 Valerian was created as Metzen felt that Arcturus' story had been effectively told in "StarCraft" and "Brood War".While Blizzard stipulated Valerian's physical description, "The Dark Templar Saga" author Christie Golden was given the freedom to develop the character as she wished.A disciple of Japanese martial arts and a keen archaeologist, he is described as "brilliant... and probably a bit arrogant for knowing it".
