Aetaos'Rau'Keres is the most feared and powerful Lord of Change in the Immaterium and is also one of the most powerful daemons in existence. Keres is insane, even by daemon standards, due to Tzeentch shackling him with numerous types of warpfuckery, to the point where he feels nothing but utter rage. Such is his power and insanity that only apocalypse cults dare summon him, because once Keres enters realspace; he will murderfuck everything on the planet he is on, neither caring if he's killing loyal cultists or the enemy, until nothing is left.

Aetaos'Rau'Keres in all of his Forge World resin glory.

In short, he's a paranoid and unfathomably pissed off exterminatus on legs (and wings).

The kicker to him is that Keres' true purpose in Tzeentch's grand schemes and his origins are his most closely guarded secrets and nobody but Tzeentch know what they really are. If anyone or anything comes close to finding out the truth about him; he will personally appear before the seeker and obliterate them and the planet they are on, just for good measure. Keres basically takes the concept of "no witnesses" to it's most illogical and hilarious extreme.

9e is out and so is the Imperial Armour Compendium from Forge World, containing shiny new rules for all your incredibly expensive resin, including this guy. The bad news? His staff has been nerfed a good deal, losing 12" of range and a point of strength, becoming d6 shots instead of 2d6 and it lost all of its special rules (aside from it being Blast now so forget about still being able to fire with it in melee). In addition, he's lost his 3++ (He still has a 4++ but doesn't benefit from Ephemeral Form), 2" of movement at full health and the ability to re-roll any failed Daemonic Rituals he attempts.

The good news? He's LESS THAN HALF HIS POINT COST FROM 8TH! Yes, you might actually be able to use this model in a regular game now that he's 600 points instead of 1500. He hasn't lost his hefty 27 wounds, his ability to reflect mortal wounds from psychic powers has been reworked so that if an enemy manifests a psychic power within 18", they take a mortal wound on a 4+, and his warpfire talons are now an anti-infantry weapon, making 2 hit rolls for every attack made with them (although they inflict 1 mortal wound per wound roll of 6 rather than d3). He also no longer has to be kept away from friendly Daemon Princes and Lords of Change and his staff now does flat 3 damage to vehicles, monsters buildings. Losing a little bit of offensive capability, durability and movement is a fair price for the significant points drop, even if you don't count the buffs he got, and he's still as good a psychic powerhouse as he was in 8th.

But now he sucks. He only casts 3 and knows 2 deny 2, a flat worse psyker than the Kairos (which can cast 3, deny 3, and knows all), who is HALF THE POINTS! Kairos also has almost the same abilities, with only 5 less wounds! Aetaos'Rau'Keres is a better fighter but that isn't the point of a Tzeentch army. Forgeworld at its finest.
