Brother Invictus from the very start was a brother devoted to his chapter in every way, he cherished the comradery of his battle brothers. He valued the lives of all those who lived within the protective range of his chapters protection, every time he was called upon to protect them he felt pride in his task to purge the evils of the universe and to leave a safe sector in his path gladly shedding the blood of his enemies in the name of both the Emperor and his great primarch.
Brother Invictus was a very promising initiate proving time and again that he would make an excellent battle brother his Sargent noting that he had a particular knack for strategically planned assaults and his input typically held incites that aided in many successful maneuvers against many foes. but it seemed that the brother had a calling higher than that of the assault squads of his chapter as he had an exceptional knack for the machine. it was with this knowledge in mind that he was offered to be sent to mars to study the ways of the mechanicum.
Brother invictus gladly accepted this roll, he knew that no mater what the strategy his brothers may employ with out their sacred relics functioning at full capacity it would all be for not. 30 years he studied on mars gaining every incite that he could so he may better serve his brothers at home in the defense of their sector. he returned home to be welcomed by his brothers who know how important his role will be in their continued efforts to keep the sector secure.
Brother invictus was very thankful for his knowledge in machines one dark day during of the Waagh! of Gutshredda as he lost his arm in battle and was pinned with several of his brothers under the orcs fire inside a bunker. while his brothers were well armed and very skilled he knew they would need every man to fight off the orks. with that knowledge Invictus quickly enlisted the aid of the medical team in the bunker and had them hastily do the required operations to attach a cybernetic arm. when the orks attacked in a frontal charge as he knew they would he was ready with 2 hands to wield weapons in the Emperors name to cleans the world of their filth.
when the brother received the call to the death watch he viewed it as a welcome opportunity to learn more of the xeno threats in the galaxy and learn more about the tech he so revered to better aid his brothers upon his return to Ultramar.
