Hesperus (Imperial Fists)
Sergeant Hesperus of the Imperial Fists led Squad Eurus while investigating a distress beacon on the Mining World Ixya. They discovered Necron structures near the beacon and escaped to the mining facility Aes Metallum while under attack by the Xenos.[1]
Preparing Aes Metallum's defenses, the Imperial forces defeated the Necrons when they attacked the facility. Hesperus thought the battle was over, when he received word that a larger Necron attack was advancing on them. Knowing they would not survive another attack, Hesperus ordered Aes Metallum's power core to be overloaded, hoping to destroy the Necron horde and give the Imperium time to return and destroy the Xeno threat. The resulting explosion destroyed the mining facility and the attacking Necrons.[1]
