Melusine

Melusine is a Lancer-class Servant in Fate/Grand Order and the fairy knight known as Tam Lin Lancelot in the British Lostbelt. Her true nature is connected to the remains of the dragon Albion rather than an ordinary human fairy.

Melusine as Tam Lin Lancelot

Confident, affectionate, and extraordinarily proud of her strength, Melusine becomes intensely attached to chosen individuals. Beneath that certainty is fear that her borrowed form and identity cannot last.

Albion's dragon power, borrowed identity, and destructive devotion

Melusine uses spear combat, flight, dragon power, and transformations that unleash Albion's destructive scale. Her loyalty to Aurora and later relationship with the Chaldea Master expose the tragedy of devotion directed toward someone unable to return it honestly.
