Dark Angels, once the I legion of the twenty original Space Marine legions. Their primarch, Lion El' Jonson, was renowned for his strategic level of tactical brilliance, but was distrusted by his brother primarchs for his secretive nature. The Dark Angels have a terrible secret that remains only known to the upper ranks of the chapter. At the very end of the Horus Heresy, half of the Legion rebelled against the Emperor under the command of Luther, a high ranking commander and Lion's own foster father. After a brutal battle, in which Lion disappeared, the traitors were sent through the Warp by a powerful warp storm and scattered across time and space. Now the Dark Angels seek to expunge their shame by bring each and every one of these traitors, the Fallen, to justice in secret. Their chapter is unique in that their 1st Company, colloquially known as the Deathwing, is composed solely of elite veterans outfitted with heavy white-colored Terminator Armor, and their 2nd Company, colloquially known as the Ravenwing, is composed solely of black armored skirmishers mounted on heavy combat bikes. Their chapter master, or Supreme Grand Master, is Azrael.
