Verulam Moy, known as The Or, was Captain of the Sons of Horus 19th Company during the Great Crusade and Horus Heresy.[1a] He was often seen alongside Tybalt Marr, Captain of the 18th Company and known as The Either.[1b]
Both Moy and Marr were 'Sons of Horus', the term for those Luna Wolves Marines who looked facially similar to their Primarch Horus. While their similarity in appearance to Horus was notable, the similarity between each other was so striking that they were considered almost twins by their fellows. This carried on into their respective nicknames, 'The Either' and 'The Or', due to the belief that they were so hard to tell apart they may as well be interchangeable. Tybalt Marr was referred to as The Either while Verulam Moy was called 'The Or.'[1b]
In fact, Moy and Marr worked so well together that it was habit, circumstances permitting, for their companies to be sent into battle alongside each other. This was not always possible due to the Wolves' practice of drawing lots to see which companies would go on missions when a smaller force than the total present was required. Two such occasions were the initial combat drop on Murder, where Moy won a place and Marr did not, and again on the mission to the moon of Davin, where Moy led the force's Devastator contingent.
It was on Davin's moon that Moy met his fate. A member of the warrior-lodge and a competent file officer, Moy had yet to distinguish himself as one of his legion's elite. His time appeared to have arrived when he was selected by the Warmaster to lead his personal security unit into the Glory of Terra, the crashed flagship of Eugen Temba. Shortly afterwards the Marines were largely separated from each other and their commander, and a lone Verulam Moy was the first to locate Temba. Temba attempted to sway Moy to the embrace of Chaos, but the Marine Captain resisted the temptation. A brief battle then took place, in which Moy was killed by the traitorous Temba. Marr was considerably shaken by the death of Moy.
