Captain Cryptus of the Emperor's Children's Twenty Seventh Company

Sergeant Cyrptos was originally assigned to the 27th Company, and had seen many victories during the Great Crusade. It wasn't until the aftermath of the cleansing of Laeran towards the end of The Great Crusade that Cryptos was promoted to Captain of the 27th Company, in part because of his expert skill with the blade and ability to kill anything that stood before him, but also for notably saving Captain Lucius' life when a Laer took him off guard, Cyrptos slicing the xenos' head clean off with one fell swoop of his combat blade. Since that day Lucius has sworn to pay him back for his actions, Lucius' arrogance does not allow for him to be in anyone's debt, except perhaps Chief Apothecary Fabius. As a result, it is common to see the two of them fighting alongside each other on the plains of war killing like for like, Lucius in an effort to remove the debt, Cyrptos to maintain his position of power over the 13th Captain. This relationship was tested when Lucius was assigned to the first wave of legionaries sent to crush the rebellion upon Isstvan III, while Cyrptos was not. Captain Cryptos was however, part of the second wave during the Isstvan III betrayal, during which Cryptos personally executed the Captain of the 11th Company, Vester. There is a belief that Cryptos planned to seek out Lucius upon the field and prove once and for all that Lucius' life was his to take. Whether they did face one another is unknown, though based on both surviving the betrayal it is unlikely; if they did fight, they did so without any real malice.
Armed with a power sword Cryptos was a born swordsman, and regarded as one of the best in the Legion, only bested by Lucius, Kaesoron and Cyrius. Records of Cryptos' actions after Isstavan V are scarce with some saying he was killed by Primarch Vulkan's Pyre Guard on that blood-stained field, though other accounts talk of him being assigned to the legion's reserve during the battle. It is not until Terra that we actually see any solid evidence that Cryptos still remained with the legion. He was present during the fighting, but all Legion records say on the matter is that he died in the final hours of the Siege but to whose hands it is unknown. The Emperor's Children have their own opinions and they keep them well, though the other key figure in Cryptos tale refuses to be drawn on his rival's fate...
