Merlin

Merlin is a Caster-class Servant and legendary magus in Fate/Grand Order. Born from a human and an incubus, he advises King Arthur and later supports Chaldea from Avalon, where he remains isolated from ordinary time.

Merlin as the magus of flowers

Playful, detached, and fascinated by human stories, Merlin can seem irresponsible because he experiences emotion differently. He nevertheless supports humanity's future and carries regret over the burdens placed on Artoria.

Avalon, illusion, and his responsibility toward King Arthur

Merlin specializes in illusion, prophecy, dream manipulation, and powerful support magecraft, with the Noble Phantasm Garden of Avalon. His relationship with Artoria, Fou, and the Chaldea Master connects distant observation with genuine responsibility.
