Linton Messer XI (SEY 2745 - 2792) was the last of the Messers to occupy the office of Imperator in the United Empire of Earth (UEE). He assumed control of the UEE in 2781 after seizing power from his father, Ulysses Messer X.
During his reign, he sold the terraforming rights of Garron II to a private company with connections to his family, knowing that the planet was inhabited by sentient beings. Revolutionary group Tide leaked footage of the resulting carnage to the media, sparking the Anti-Messer Revolution. During the uprising, Linton was killed in office.
