Lord Eversight's gifts are many, but the main one which gives him his name is precognition. This is an ability that many psykers share, but hos is so finely tuned that it is nearly perfect. As he leads the Dread Legion in the cleansing of Octrum Beta, he moves like a specter in the enemy's midst. Bolts, las, plasma, and missiles flicker past him, missing by inches as he slaughters the forces of the Executioners of Vengence. It is a display of dominance that would be impressive against the cultist cattle the Traitor Marines command, but he butchers transhuman as easily as he does baseline.
A chain axe misses him by a hair before he flicks out his hand and wipes the Traitor Marine, swinging it from existence with a blast of black fire. A cultist fires round after round at him from a heavy bolter. He turns the bolts into mist before sending the mist back at the cultist and a half-dozen of his allies as burning promethium that engulfs them. A Hellhammer tank comes at him, firing on him with its main cannon, only for the massive shell to stop inches from his eye lenses before turning mid-air and flying back into the barrel, gutting the tank with the insuing explosion.
During all this, the Dread Legion passes judgment, their Dread Sight seeing into the souls of all they lay their eyes on. Those who remain faithful to humanity are marked in gold, while those who have betrayed their kind burn red. Those that glow red are soon little more than red ruin. Street by street, city by city, the Emperor's Wraith Given Form purges Octrum Beta of all enemy life, seen and unseen. But there are no parades, no cheering crowds, and no triumphant celebrations because dread has come to this world. Dread that affects the innocent and the guilty alike. It covers it like a veil, making those who are weak-willed and susceptible to the whims of the Archenemy but have not fallen look deep into their souls and find themselves wanting. The number of suicides in this world is in the tens of thousands because of this. From the highest echelons and holiest orders to the lowest gutter rat, the dread brought by the Drear Legion acts as a cleansing flame for Octrum Beta, sparring none from its dark, revealing touch.
