Sarren
Sarren was the Colonel of the Armageddon 101st Steel Legion Imperial Guard Regiment at the onset of the Third War for Armageddon.[1b]
During the initial mustering of Imperial units to defend Armageddon, Sarren and the 101st were among the regiments tasked with defending Hades Hive. However, it was eventually decided (following a recommendation by Commissar Sebastian Yarrick) to abandon Hades to the enemy. Sarren was instead asked to take command of the defence of Hive Helsreach after Colonel Insan of the 121st Steel Legion suddenly died of heart failure.[1a][1b]
In the defence of Helsreach, Sarren was the highest-ranking Astra Militarum officer present in the city.[1b] Whenever he had to act in the field, he did so from the Baneblade Grey Warrior.[1c]
