New Archaeon Model

where the fuck is slaanesh

seriously though, that thing is bonkers

That flying birdguy is fucking jacked

Yeah dude, that's Dorghar his daemonic mount...only upgraded to warp-y chaos dragon level. Kinda loving the 3-headed dragon thing he's got going on, not gonna lie...but might GS some tits onto it for Slaanesh.

I'm pretty sure GW totally axed Slaanesh from the very beginning - at least for AoS. I remember some other rants/pictures in various forums online about the symbols etc being removed from everything Chaos related. I think there was another one added though, or last I heard that was a speculation at least.

Either way, obviously still put tits on it.

So the way its framed in AoS is that Slaanesh was captured/imprisoned by the elves (specifically, Tyrion and Teclis in Avatar forms) so that he couldn't torment their souls any longer; because of this, his power has waned, and the armies/demons of slaanesh are weaker. But, in AoS, the Horned Rat is powerful enough to rival the chaos gods, and is trying to be counted among their number - so his symbol replaced slaanesh in a couple images in the AoS booklet. 

But Arcaheon refused the horned rats blessing when they crowned him as the ever chosen and sent him into Azyr to destroy the Sigmarites, which is why only the remaining 3 chaos gods are represented on his mount. 

But there is ample room for GW to have slaanesh released in a future campaign book, and Slaanesh is obviously a key player in 40k, so he's certainly not gone for good. Just another strange nuance to the AoS story that is wholly unnecessary, but for whatever reason was written. 

Its just speculation on my part, but I thought the reason they might have done it was to avoid the problems caused by the nude/sexual models in the Slaanesh line. AoS certainly seems to be designed to be accessible to a younger audience, and as such it makes sense that they would take the boob worms and vagina monsters off the shelves.
