A Noyan-Khan (Lord Commander) of his Legion after the death of Giyahun, Jemulan was born on Terra as opposed to Chogoris and commanded the Horde of the Earth. During the Heresy Jemulan proved somewhat sympathetic to the Terran-born Lodge members led by Hasik Noyan-Khan and Torghun Khan who were preaching loyalty to Horus, ignoring Shiban Khan's concerns about them. However when chaos gripped the legion over Prospero, Jemulan proved loyal to Jaghatai Khan and led Keshig units in restoring order.
