Abyssal Sons

The Abyssal Sons, formerly known as the Blades Eternal. One of the thirty loyalist chapters that were sent on the Abyssal Crusade in 321.M37. After spending hundreds of years fighting the Emperor's enemies within the Warp they finally succumbed to the chaos corruption and were transformed into the chaos warband now known as The Abyssal Sons.

Xiphos Falcata, chapter master of the Blades Eternal discarded his old name when the chapter turned to chaos and took the new name of Coriah Nyx. For he was no longer an imperial dog under the command of the False Emperor, he was the Lord of the Abyss, born out of chaos. For Centuries Coriah led his warband within the warp, slaughtering anything before them. Slowly gaining the favour of the chaos gods and growing ever more powerful. Untill finally his devotion payed off and he became a champion of chaos. His ambition to destroy the realm of the False Emperor attracted other forces within the warp and soon their gathered strenght would be enough to enter real space and carry out this ambition.

In 100.M42 their incursion into real space began as they materialized just outside the Numantian Sector in Segmentum Pacificus. The Cimmerian Crusade had begun.
