Regulus was the Mechanicum representative to Warmaster Horus and the 63rd Expedition during the Great Crusade.
雷古勒斯是大远征期间战帅荷鲁斯和第63远征队的机械教代表。
After being swayed with promises of STC's from the Aurelian Technocracy, he pledged the Mechanicum's service to Horus. Shortly before the Isstvan III campaign, Regulus was dispatched by Horus to Mars and assisted in swaying the Fabricator-General Kelbor-Hal to the Warmaster's Side. Later, Regulus returned to Mars with a daemonic virus, aiding Kelbor-Hal's forces in the Schism of Mars.
在被奥瑞利安技术联盟的STC的承诺所动摇后,他承诺机械教将为荷鲁斯服务。在伊斯塔万三号战役前不久,雷古勒斯被荷鲁斯派往火星,并协助铸造将军凯尔博·哈尔说服到战帅一边。后来,雷古勒斯带着一种恶魔病毒回到了火星,帮助凯尔博·哈尔的部队进行了火星分裂。
Regulus led a force of Sons of Horus sent to gain access to the Wrought, a weapons cache maintained by Vulkan during the Great Crusade. Although he discovered the vault, he was unable to gain access until he infected the Forgefather T'kell with a malicious scrap-code and forced him to open it from the inside. The Iron Father Kastigan Ulok intervened to defeat the Sons of Horus, having tracked Regulus to the system hunting the 'prime' Regulus that controlled his many facsimiles. Understanding that he had no hope of survival with the arrival of the Iron Hands' Battle Barge in-system, Regulus retreated to his sanctum to purge his data-core. Originally intending to take him alive to extract information, Ulok killed the adept instead - satisfied with the data he had managed to intercept which revealed the existence of the Artefacts of Vulkan, weapons he believed he could use to kill Horus.
雷古勒斯率领一支荷鲁斯之子部队,被派去进入沃坎在大远征期间维护的武器贮存。尽管他发现了这个密库,但他无法进入,直到他用恶意废码感染了铸造之父特'凯尔,并迫使他从内部打开它。铁父卡斯提根·乌洛克介入击败了荷鲁斯之子,他追踪雷古勒斯到了一个星系,追捕控制他许多分身的“主要”雷古勒斯。意识到随着钢铁之手的战斗驳船进入星系,他已经没有生存的希望,雷古勒斯撤退到他的密室清理他的数据核心。乌洛克原本打算活捉他以获取信息,但却杀死了这位专家 — 他对自己截获的数据感到满意,这些数据揭示了沃坎造物的存在,他相信这些武器可以用来杀死荷鲁斯。
