Alberich Harster was an Imperial Guard General and native of Cadia who was a member of Cadia's High Command during the 13th Black Crusade. A grizzled hard veteran of many campaigns, Harster arrived on Terra during the Crusade in a bid to bring 500,000 reinforcements to the front. While on Terra, he met with Chancellor of the Imperial Council Lev Tieron to make the arrangements. Despite knowing that Cadia would likely already have fallen by the time he arrived with the reinforcements and that only death awaited him and his men, Harster departed with his men all the same.
