Description
Caules Forvedge Yggdmillennia, eldest son and backup heir to the Forvedge lineage, was destined to support his sister Fiore, whose extraordinary Magic Circuits were shadowed by leg paralysis. Deemed mediocre by his father—a symbol of the family’s fading prestige—he reluctantly embraced magecraft as an obligation, only to discover a measured appreciation for its mechanics, viewing it as a practical tool rather than an all-consuming purpose.

Thrust into the Great Holy Grail War in *Fate/Apocrypha* when Command Spells spontaneously marked him as Master of Berserker of Black, his hesitant participation hardened into resolve. Prioritizing survival and mutual trust with his Servant, he navigated the conflict’s chaos. Post-war, he dismantled the Yggdmillennia clan, bargaining with the Mage’s Association to spare its members while accepting quasi-hostage status at the Clock Tower. There, Lord El-Melloi II identified his latent gift for Electricity Magecraft, a departure from his family’s spirit-summoning heritage. This evolution birthed his signature “Crafted Tree,” subtly influenced by an alternate-world link to Frankenstein’s “Blasted Tree.”

In *Lord El-Melloi II’s Case Files*, within a timeline devoid of Yggdmillennia, Caules assumed the Forvedge mantle after Fiore renounced magecraft. Despite his unremarkable circuits contrasting her brilliance, he honed his electrical aptitude under El-Melloi II’s tutelage. Amid peers like Flat Escardos and Svin Glascheit, he voiced yearning for normalcy even as he faced supernatural crises, including the Mystic Eyes Collection Train incident.

A decade post-war, he partnered with Atlas to pioneer “Codecasts,” fusing magical and technological systems. Though attributing primary development to Atlas, he conceived the foundational concept. Retaining alliances with former Yggdmillennia associates, he advised Lemina Eltfromm in her Holy Grail War, strategizing against Knights of the Round Table using insights from his clash with Mordred.

His journey wove familial duty with self-discovery, transitioning from a reluctant magus to a deft practitioner maneuvering Clock Tower politics. Pragmatism and adaptability tempered his perceived mediocrity, forging occasional ingenuity through mentorship and exigency—a testament to resilience amid the tension between legacy and individuality.
