Summary
Caules Forvedge Yggdmillennia served as the Master of the Black-class Servant, Berserker, during the Great Holy Grail War. Born as the eldest son of the Forvedge lineage, he was originally designated as a backup heir and tasked with acting as a caretaker for his older sister. After she ascended to become the family head and rose to a prominent position within the Yggdmillennia clan under Darnic, Caules sought to forge his own path rather than remain a mediocre magus with no prospects. His plans were disrupted by the Holy Grail War; although he initially traveled to Romania merely as support, Command Spells appeared on his hands upon arrival, compelling him to participate as a Master against his will.
