Yeah, and that's not even getting into how the Druuchi kinda splintered when Morathi finally made her play for godhood and various factions of them ended up all over the place after Chaos got banished. Or, as you observed, the inevitable Settra Wars, the conflict brewing in the east with the empowered Ogre Dominion that looted a ton of Dawi-Zharr tech during the warring there, their conflicts with Ind, Cathay ending up subjugating a good amount of the pseudo-mongols north of them since their Chaos leaders got banished and using the new north-facing land passages to pull some trading and conquesting off... lotta stuff happening there, enough that I'd be at it for years if I ever analyzed it in detail.
Most definitely, and funnily enough the threat he poses (coupled with the various greenskin hordes that have grown to frightening sizes) will provide significant impetus to the various factions now residing in the Old World to put their old quibbles aside, stop fucking about, and make the world a better place to live.
They're guaranteed to get more esoteric in the future, but for now just look up macuahitl and picture various sizes of those with a black/gold color scheme.
He probably won't end up featuring in any Primarch backstories, but Archaon does have a role to play in this galaxy. Not many beings have been in the same positions he's been in, being first immensely favored by a mortal god and then shaped by the powers of Chaos into their vessel for the apocalypse, much less survived relinquishing both of those mantles. He's in a unique position, with uncommon capabilities despite the rescinding of his dark blessings. You don't get filled with Warp-juice until your presence makes the world quake and not come out of it with something different about you.
I don't mind so much as long as it's related to the thread itself, but yeah mayhaps time to divert it to the game's thread if you intend to keep discussing it.
