Master Spy

A Master Spy (unknown – 1916) operating on behalf of the German government, in London, during World War I, was the head of a Templar spy network and a Sage who had fallen completely under the control of Aita's spirit. In 1916, his organization was dismantled by the Assassin Lydia Frye, at the behest of Winston Churchill, and the Master Spy, assassinated.

In 2015, Juno thanked a Helix initiate for discovering his fate, and added his life, and in doing so a fragment of her late husband, to herself.
