Changes

The Shadowmasters or '''Mor Deythan''' were a unit of Raven Guard during the [[Great Crusade]] and [[Horus Heresy]]. They were ordinary battle-brothers who had [[Corax|their primarch]]'s ability to '''Shadow-walk'''. It was a quirk of the gene-seed in a few [[Deliverance|Deliverancian]] born Raven Guard that had more than just the standard gene code. One unique trait about the Shadowmasters is that they were completely unknown to their own legion. The marines were selected for testing "Thermal Technology" which was considered "highly temperamental. Corax and select apothecaries are the only marines in the legion that knew of the group at the time of the [[Horus Heresy]]. The Mor Deythan acted as an elite stealth team and saboteurs and communicated through '''Stalk-Argot''' while working in concert with the rest of the legion. The Shadowmasters performed flanking maneuvers and sabotaged columns of rogue [[Skitarii]] on [[Constinax]]. {{Fn|20}}
