Historical Depiction
Jack Frost is known to be a brutal personification of winter and merciless to those who come face to the howls of his snow. Normally, he be would be summoned as an alter ego, however, due to his vessel being a child, the personality changes that come along with being a pseudoservant ultimately changed his class to a caster. The vessel in which he lies is the body of his former master from another grail war, a story for next time.
