Declassified: Regius Cohortis

A phrase always followed by 'To serve the Emperor's will'. Yet for these marines, the statement changes. Meet the 21st Legion of the Legiones Astartes. Created during the time leading up to the betrayal of Primarch Horus and his heretical crusade. While the Human Webway was a project he focused on, there was one kept secret from the entire Imperium: creation of another legion. The Primarch of which, was never woken. These men are the Regius Cohortis. In tribute to a language long unused by the Imperium.

Latin for Royal Guard. This is their story.
