Waver Velvet

Waver Velvet is the Master of a Rider class servant in the 4th Holy Grail War.

The future Lord El-Melloi II, Waver Velvet is a nineteen year old student at Clock Tower, an institute of the Magus Association, and mage with a recognized magical lineage of three generations. While he is talented, but not recognized by his peers or lecturers.

An intelligent young man, Waver came up with the revolutionary concept that a mage's power could be increased through effort, experience, and knowledge rather than increasing magical potential through that of a mage's heirs. His idea is dismissed by his lecturer, the nobleman Kayneth Archibald El-Melloi, who tears up Waver's manuscript without another thought.

When Waver discovers that El-Melloi will participate in the fourth Holy Grail War in Japan, Waver steals the artifact El-Melloi intends to use to summon his Servant and runs off to Japan. Intending to win the Holy Grail in order to force the Magus Association to recognize his genius, he takes the stolen artifact and summons Rider-class Servant, Iskander.

Though an adept mage, his confidence in his own skill comes off as arrogance. Waver is not courageous by nature and somewhat short-tempered, which makes it difficult to control the overbearing Iskander, who has no interest in the Holy Grail. The two of them stay with Glen and Martha Mackenzie, an elderly Canadian couple living in Japan, for the duration of the war. The couple, thanks to Waver's magical abilities, are under the impression that he is their grandson.

As Lord El-Melloi II, Waver Velvet appears in Fate/hollow ataraxia as Rin Tōsaka's lecturer at the Magus Association and possesses an interest in the popular culture of Japan (though he likes little else about the country). He is responsible for dismantling the Holy Grail after the fifth Holy Grail War.

Servant
Waver's servant is Iskander, who was summoned using a mantle once worn by Iskander. The artifact was originally Lord El-Melloi's and stolen by Waver, who intends to prove that his teacher is wrong.

Iskander, the King of Conquerers, is noble and physically overbearing. He is an enormous man who has little interest in the Holy Grail and cares more about conquering the world again, especially now that he realizes the world is much bigger than he was aware of during his life. He is especially fascinated by ordinary aspects of modern life and intends to inform the world of his return, much to Waver's chagrin.
