Achellus
Achellus was a Techmarine who served in the Ultramarines Third Company, under Captain Jehnnus Ardias, when the Company was stationed aboard the Imperial Navy Emperor Class Battleship the Enduring Blade[1a] (the flagship of Battlefleet Ultima Primus) when it received a request for aid from the planet Dolumar IV, which was being attacked by the Tau.[1b]
Once there, the Ultramarines prepared to battle the Tau, who had managed to board the Enduring Blade, but Epistolary Delpheus, plagued by visions that a more powerful enemy would show itself aboard the ship, managed to convince his old friend Ardias that they needed to save their strength and avoid fighting the Tau. Ardias was convinced by Delpheus and told his company to stay where they were and let Captain Mito and the Raptors Chapter's Fifth Company, who were also stationed aboard the Enduring Blade, deal with the Tau.[1a]
This would prove fortunate as when the Battlefleet was forced to open diplomatic talks with the Tau, the heretic Meyloch Severus, Planetary Governor of Dolumar IV, completed a Chaos ritual that summoned a warhost aboard the Enduring Blade that soon overran the doomed ship.[1c] Ardias gave the order to evacuate the Enduring Blade[1d] and Achellus managed to escape with Ardias and his Company[1f] before it was destroyed[1e], taking part in the ensuing battle when the Chaos warhost invaded Dolumar IV. On the planet he joined Veteran Sergeant Larynz's squad as they charged a pit held by the Iron Warrior Pereduz and a group of Chaos Space Marines. When they arrived, however, the pit was empty save for a device buried into the sand that filled it. As Achellus examined the device, Pereduz, hidden nearby, activated it, resulting in a massive explosion that instantly killed Achellus, Larynz and their squad.[1f]
