Caster of Black
Caster of Black serves as the Caster-class Servant for Roche Frain Yggdmillennia in the Black Faction during the Great Holy Grail War of Fate/Apocrypha.
His appearance is immediately striking—a featureless mask with no openings for eyes or mouth, paired with a full-body suit and blue mantle. The mask makes it genuinely impossible to read whether he's feeling anything at all, which sets an unsettling tone for any interaction.
Personality-wise, Caster is strange. He's the type to just nod instead of answering when someone talks to him. In life, he had a weak constitution and a pessimistic outlook, which left him wanting nothing to do with other people. He can hold a conversation if he has to, but there's no real warmth or feeling behind it. His singular focus on one specific school of thaumaturgy as a magus meant he never had to worry about the day-to-day stuff most mages deal with—he had his specialty, and that was it.
