Oiagros Zevon

Wizard is a mysterious masked man who styles himself as a “magician”, and is a financial supporter of Peace Mark. He possesses vast information and assets, and is said to be very reliable, but his hidden background and identity have many grounds for suspicion. He toys with the two “Oz”s, Oldrin Zevon and Orpheus Zevon, whose identities and pasts he is apparently aware of. He pilots the black Knightmare Frame, Agravain.

In the 4th chapter of the photo story, he is revealed to actually be "Oiaguro Zevon", the uncle of Orpheus and Oldrin and the leader of the Britannian organization "Pluton", which carries out dirty jobs for the Britannian royal family. He is also the one responsible for killing Orpheus' lover Euria, and is the enemy that Orpheus hunts and seeks revenge against.

In reality, he is tortured by a guilty conscience for killing his older sister in order to take over as the head of the family and furthermore killing his nephew (or so he believed at the time) on a mission. Because of this, he commits the contradictory actions of supporting an anti-Britannian organization despite being the leader of Pluton and supports Orpheus in various situations as a way of atonement.
