Necrons are already nightmare fuel, and yet they still get underrated. They do not breathe, they do not sleep, and they erase you with tech that feels like magic.
So, when the lore says there is a thing that makes even Necrons fearfully double check their own reality, you pay attention. Additionally, the 500 Worlds of Ultramar are about to learn this the hard way. This summary of the article digs into why Nekrosor Ammentar is treated like a myth until it is suddenly not.
A Legend That Turns Out to Be Very Real
A lot of Necrons apparently dismiss the Nekrosor as folklore or a cautionary tale. However, Ultramar does not get that luxury. Ammentar is described as completely capable of ripping through flesh and blood. So, the text frames it as death incarnate, not just a scary Destroyer with a cool name.
It also opens with a key point. Necrons are terrifying to normal people in the 41st Millennium. Therefore, something that terrifies Necrons is a threat on a different tier.
The Destroyer Virus, but With a Mind Still Intact
Ammentar is afflicted by the same maddening virus that turns Destroyer Cults into pure killing engines. However, it is not fully enslaved by the urge the way other Destroyers are. So, it has the worst combination. It has the hunger for annihilation, and yet it also has a high functioning mind that can plan.
Some Necrons even suspect it was the first to fall. Therefore, it might be the origin point for the entire Destroyer curse. That is not confirmed, because records do not exist. The only one who might know is the Silent King, Szarekh, and the text jokes that he is not exactly chatty.
The Pall of Psychosis and Forced Conversion
The real horror is what happens around Ammentar. A “pall of psychosis” follows it, and it twists Necron minds in its wake. So, everyone from lowly tomb world workers to Overlords can get warped into raging death addicts. Additionally, many do not even realize their protocols have been overwritten at first. Then it is too late, and they are gleefully strapping hyperphase blades onto themselves.
If Necrons do not fall in willingly, they get pushed. Ammentar’s enthralled Crypteks forcibly convert others into Destroyers. So, it is not just spreading madness. It is actively building an army by stealing minds and rewriting them. That is why it is deeply unpopular, and it absolutely earns its reputation.
There is also a fun little nightmare footnote. Legend says Ammentar has corrupted the master programs of whole tomb complexes. So, it is not only people. It might be infrastructure too.
Nightbringer Obsession and the C’tan Shard Hunt
At some point, either through age or an ancient injury, Ammentar develops a near religious obsession with the Nightbringer. That is extra gross to other Necrons, because the Nightbringer is the deadliest of their ancient star god enemies. However, Ammentar does not just admire it. It has taken up the Nightbringer’s mantle and wants total eradication of organic life.
That crusade has a clear goal. Ammentar wants to gather every scattered C’tan shard and unleash the Nightbringer anew. So, it is basically doing the galaxy’s worst scavenger hunt. The implication for Ultramar is nasty too. If you are wondering whether there is a shard hidden under Ultramar’s worlds and Ammentar is coming to collect, the text basically says yes, you are thinking correctly. Additionally, the Ultramarines do not truly understand what is about to hit them.
A Whirlwind of Weapons, Speed, and Predatory Intelligence
On the tabletop story side, Ammentar is described like a mobile slaughterhouse. It is festooned with weapons, including barbed claws, the Unmaker Gauntlet, enmitic disintegrators like those used by a Hexmark Destroyer, and a whip like bladed tail. So, every limb is a problem.
Its infectious madness also amps up its Destroyer allies. Therefore, the units around it hit even harder, cleaning up whoever survives the initial blitz. The vibe is clear. Ammentar hits so fast that people die before they can even raise blades.
However, the scariest part is not the violence. The scariest part is that Ammentar is not a dumb beast. Other Necrons fear its predatory intelligence and occasional lucidity. So, it can actually pursue a long game plan. Additionally, if it succeeds in wiping out all organic life, the Necrons would have nothing left to rule. Or, as the text snarks, nothing left to look down on.
Summary
Nekrosor Ammentar is terrifying because it combines Destroyer madness with real intelligence. So, it spreads psychosis, overwrites protocols, and even forcibly converts other Necrons through enslaved Crypteks. Additionally, it is obsessed with the Nightbringer and is hunting C’tan shards to bring that horror back. On the battlefield, it is fast, heavily armed, and it drives its allies into greater carnage. Meanwhile, the bigger fear is strategic. If Ammentar’s crusade works, the Necrons win a galaxy of ash and silence.
And here is the punchline for hobbyists. Ammentar goes up for pre order this Saturday, and the joke is that it is already too late to prepare. So, if you play Ultramarines, you might want to start practicing heroic last stands.
