Fabris rules as king of the Tribe of Light. He is Maria's father and Mew's grandfather, possessing short brown hair that greys with age, brown eyes, and fair skin, having lost his right arm in combat. Later, he wears a unique red crown.

He shows deep care for his family, especially Maria and Mew. Yet, witnessing the warrior Sharon's prowess from the opposing Tribe of Shadow sparks a dangerous obsession. This fixation leads to distinct actions: coating a dagger with an aphrodisiac to wound Sharon in the game, and attempting to rape her during an assault on the Shadow Tribe's realm in the anime. That same assault claims the life of Hyde, Astral's close friend.

An older, highly experienced knight considered stronger than Kaiser or Sharon, Fabris orchestrates repeated assaults on the Shadow Tribe's underground domain. Two decades after losing his arm, he encounters an amnesiac Astral on the surface. Recognizing an opportunity, Fabris manipulates Astral—mistaken for the legendary Pollux—presenting him as a weapon to breach the Shadow Tribe's sealed borders.

His story concludes without explicit redemption. After Astral regains his memories and unites the tribes against a greater threat, Fabris's ultimate fate remains unaddressed. His legacy endures through his ruthless wartime conduct, his familial bonds, and his pivotal role in perpetuating the tribal conflict.
