In 999.M30, Dantioch led the Iron Warriors to bring the Gugann system to compliance. A Hrud migration through the system put a halt to that effort. Under orders from Perturabo to take the system at all costs, Dantioch ended up losing most of the legionaries under his command, several ships, and suffered an estimated three thousand years of Hrud entropy-induced aging. The 51st Expeditionary Fleet was effectively destroyed.
He subsequently questioned Perturabo's purge of the Hrud in the region, asserting that the purge prompted the migration and inferring that Perturabo or the Emperor himself had made an error in committing to the campaign. His name was expunged from records and the Terminator armour intended for his use was reassigned to Barban Falk. The last orders Dantioch received from Perturabo were to take the remainders of his command to Lesser Damantyne and bring it to compliance and to never show his face again. In the process of rendering Lesser Damantyne compliant, Dantioch designed and led the construction of the Schadenhold. When Warsmith Idriss Krendl came to the fortress, ordering that it be used as a resupply point for Horus's armies, Warsmith Dantioch refused to betray the Emperor. Krendl told him that he would crush his fortress in the name of Horus.
Dantioch defended a bloody siege of the Schadenhold, spending the next 366 days commanding his meager forces against the 51st Expedition Fleet and the 14th Grand Company. Towards the end of the siege an Emperor class Titan was deployed against him, and subsequently destroyed. When the fortress was about to fall he teleported himself and a few others onto the traitor's flagship in orbit and was able to commandeer the vessel. Dantioch set course for Terra with the aim of assisting the Emperor in fortifying the Imperial Palace against the traitors.
Dantioch eventually found himself on Sotha, helping the Ultramarines determine the function of an ancient xenos structure underneath Mount Pharos. He also became allies with Alexis Polux, overcoming Polux's reactionary hatred of the Iron Warriors by finding common ground between them. [2x] Through his work on the structure, known as the Pharos, he became a linchpin of Roboute Guilliman's Imperium Secundus due to the Pharos's ability to send not just messages, but matter across vast distances of space. He was later killed during the Battle of Sotha, sacrificing his own life to thwart the Night Lords of Krukesh by overloading the Pharos after his own capture.[4a] Dantioch died in the arms of Polux, his former enemy mourning his fallen brother.[4b]
Barabas Dantioch was recognised as the first Warden of the Pharos and a hero of the Great Heresy by Guilliman's own decree. His mask remained within the Pharos atop the 'Aegidan Oath' sworn by Oberdeii as the new Warden of the Pharos.
