Natase was dispatched at the behest of Eldrad Ulthran to rendezvous with Indomitus Crusade Fleet Primus under Roboute Guilliman. Despite great apprehension among the Imperials, Natasé was allowed aboard the Dawn of Fire and gave his warning on the imminent disaster on Gathalamor.
Years later during the Plague Wars Natase was still part of Guilliman's retinue in Indomitus Crusade Fleet Primus. Still dutifully carrying out his duties given to him by Eldrad, he had nonetheless reached his limit of endurance by being around Humans for so long. He opposed Guilliman's plan to interview a Daemonhost in order to gather intelligence on the intentions of Mortarion and Ku'gath.[3a] He later aided Imperial forces on Iax alongside Decimus Felix and Donas Maxim.[3b]
