Golbez (????? Gorub?za), real name Theodor Harvey (?????????? Seod?ru H?vi), was born to Kluya and Cecilia. While growing up, he always wondered why his father was fascinated by the moon and was unaware of his father's origins as a Lunarian. His father would not tell him until he had mastered the arts of magic. Theodor boasted that he can cast magic, but when his father asked if he's even mastered the Cure spell, he admitted he can't. When Theodor returned home afterwards, he saw his mother collapsed on the floor. She told him she was alright, and that she's just tired from carrying her next child. Excited about having a brother, Theodor went to bed.

Kluya was attacked by the very magic he had taught to humans. When Kluya wondered if it was right to teach the people of Earth magic, Theodor assured his father it was, comforting his father in his final moments. As Kluya passed on, Theodor tried to cast Cure on him, but was unable to. The villagers of the town took care of Theodor and Cecilia afterwards, and when Cecilia finally gave birth, she died in labor. Unsure what to do, Theodor took the child and ran away. As he fled, he heard a voice telling him that the baby was the one responsible for taking his mother and father away from him, and that he was worthless for letting it happen. The voice then told him that he was "an insect born from a dragon's corpse", and declared that his new name was Golbez. The infant grew to become Golbez's brother Cecil Harvey.

In reality, the voice was Zemus. Taunted by Zemus' voice and ashamed of his actions, Golbez fled civilization. Eventually, combined with Golbez's Lunarian blood and his hatred of his younger brother, Zemus was able to influence his mind and take control of him. Golbez subsequently lost many of his memories and began to gather the Crystals to summon the Giant of Babil. The Giant would then depopulate the planet so that the Lunarians, presumably under Zemus' control or command, could live there rather than stay in stasis inside the moon.
