The son of Asa Hon and the Neanthal and Ragaz. Wahan Tribe member in Iark and an outsider of Arthdal. Ta-gon’s strongest enemy in the future. If i say something inappropriate I learned it from my aunt shirt. The result of a heterogeneous love of heterosexual at Arthdal. Eun-seom is a mixed race between Saram (humanity) and Neanthal, an Igutu who was born in the Great War. According to the prophecy of Arthdal. “The child was born on the day of the Blue Comet (Supernova) appears, will bring disaster.” And on the day Eun-seom was born, Blue Comet has shone brightly in the sky. Eun-seom’s mother, Asa Hon, somehow escaped Arthdal and went to Iark to save Eun-seom. But Asa Hon was faced with death during his trip to Iark.
