Marshall Leon (2753-2891) was a Human politician who served as Imperator of the United Empire of Earth from 2801 to 2811. Leon started his career in social services in 2774 and worked up to the Governors Council of Reisse (Rhetor III). From there, he was elected as Senator where he served from 2787 to 2793, and then as Diplomatic Secretary of the UEE under Imperator Erin Toi from 2793 to 2800. He conceived of the Ark during his time as Diplomatic Secretary, obtaining approval for its construction from the Senate in 2794. During his campaign for Imperator, he was endorsed by Toi on the strength of his diplomatic achievements and his work on the Ark. He attended the opening ceremony for the Ark during his first year in office. When Leon finished his term as Imperator, he joined the Ark’s Board of Directors, a position he held until his death.
