Necrons dealt with on Hexis

The Novgarod 1567th stationed on Hexis first became aware of the interlopers behind their lines when a roving patrol blundered straight into them as they rounded a rocky outcrop. The encounter should have been fatal but instead of attacking the sizeable Necron force completely ignored the Novgarod patrol, as if failing to consider it of any interest or relevance. Passing within feet of the frightened Novgarod the Necrons simply continued on their way. Their complete failure to react to the armed patrol was not the only thing out of place. These Necrons wore dynastic colours not seen before on Hexis or elsewhere in the sector and seemed to move with a complete absence of sound. They trudged forward at a steady and predictable gate but if an observer were to blink or look away for a moment the eeire xenos would suddenly be somewhere else, as if having moved with impossible speed in the blink of an eye. Although unsettling to look upon it was only when reviewing pict feed that their true strangeness was revealed, seeming blurry and out of focus, in some frames suddenly invisible and in others semi-transparent or clouded by static.

Despite the increasingly numerous Imperial forces shadowing them the Necrons continued to ignore the humans, roving about the barren ash wastes as if at random and going from one rocky outcrop to another. It was only when a regiment of Novgarod supported by tanks barred their path that the xenos finally reacted to the human presence, if only to stop and idle for a few minutes. Then, without warning they attacked.

Some of the Necrons marched steadily forward, firing their weaponry into the Imperial lines whilst others seemed to stutter forwards at an impossible rate, though when interviewed later no trooper ever saw one of them moving faster than walking pace. One squad of guardsmen who had been busy changing containment capsules on their plasma guns looked up to find the canoptek constructs that had until that point been scanning the rocky outcrops suddenly in the midst of them and didn't even have time to scream in terror before dying to the sweeping void blades mounted on their tails.

Despite the unsettling nature of their foe the guardsmen kept good discipline and eventually all of their alien foe lay dead. Except, they didn't as the moment someone blinked or looked away the damaged and dismembered remains of their enemy had simply vanished leaving only dead guardsmen and the scouring of weapon impacts on the rocky terrain as evidence that any battle had ever taken place.

The incident was reported to High Command where it was marked as low-importance by a junior intelligence officer and immediately lost amidst mountains of other reports being received from the front lines.
