#webway

I like how in 30k the Webway and any technology surrounding it is so mysterious and the Emperor spends a lot of time puzzling over it and keeping Magnus out of it and it's just oh-so-strange. Also: danger, Will Robinson!

And in 40k the whole Chaos bunch practically lives in there like some feral opossums inhabiting your walls. Fabius has so many portals to the webway he has to clarify which one he's talking about when he sends his guys to "defend the webway-portal!". Or Lucius' sorcerer just drives the whole Strike Cruiser with all the demons that cling to it right through it, like Karen parking over three disabled spaces at Walmart. Or the Thousand sons crawl around in it and lick its walls (probably).

So, much advanced! Many webway-understanding!

The Emperor’s Great Work

Although the Horus Heresy was ignited by the product of a conspiracy by the forces of Chaos, there were precipitating factors that helped push many of the Legio Astartes towards rebellion.

The first was the Emperor's return to and seclusion on Terra, working on a secret project that he refused to share with any of his Primarchs, including his most favored son Horus, whom he had named Warmaster.

The ultimate objective of the Webway Project was for the Emperor to completely sever humanity from the Warp in its entirety, depriving Chaos of its power. This would come as the Emperor guided the species in its evolution into a fully psychic race, assuring its ascendancy on the galactic stage.
