As one of the vaunted Crusader Host, Brother Crius stood as the representative of the X Legion upon the soil of Holy Terra, but when he learns of the death of his beloved primarch Ferrus Manus at the hands of the traitors, his stoic, mechanical grief imbues him with the strength and resolve to undertake a special mission on behalf of Rogal Dorn himself. Striking out into the stars, he searches for any signs of his lost Iron Hands brethren, hoping to bring them back to Terra to aid in the final defence of the Palace.

The Dark Angels and the Night Lords fought one another to a bloody stalemate during the Thramas Crusade and, though the Lion eventually claimed victory, it left both Legions scattered and under-strength.

The Pharos stands as a beacon of light in the darkness, a whisper of hope in the silent void, a bastion of defiance in the face of treachery. Without it there could be no Imperium Secundus - why, then, do the masters of Ultramar know so little about its operation, or the dangers it could present? Young Oberdeii and Tebecai, Scouts of the 199th Company, descend into the depths beneath Mount Pharos in search of the truth...though it may haunt them for all time.

The primarch Angron: gladiator-king and Horus' lunatic attack dog. Never having hidden his resentment for his brothers, he now carves a bloody swathe through the galaxy in the Warmaster's name, with the Heresy providing a convenient excuse to indulge his love of brutal warfare. When they are tasked with a secretive mission alongside the Word Bearers Legion, the World Eaters' violent tendencies soon attract the attention of xenos raiders, troubled by the portents surrounding the primarch's berserk fury.

The Thramas Crusade draws to its inevitable conclusion, with the forces of the Dark Angels and the Night Lords locked in a struggle which neither side can abandon. The Night Haunter lies comatose after being mauled by his primarch brother Lion El'Jonson, and in his absence it falls to Sevatar and the remaining members of the Kyroptera to command the Legion.

Amon Tauromachian, one of the Emperor's elite Custodian Guard, returns to the Imperial Palace after a year on one of the Blood Games by which these exalted heroes train.

With the galaxy at war and half the Imperium's armies in rebellion, any hint of heresy on the Throneworld must be stamped out.

The Dark Angels Legion is couched in layers of mystery and secrecy, harkening back to the days of the knightly orders of Caliban that helped to raise their infant primarch. But Lion El'Jonson's greatest strength often proves to be one of the most divisive issues amongst his sons - rarely can any two commanders agree upon one single course of action from the start.
