Guilliman would have gone Fulgrim on Nocturne, making it a hyper efficient industrial midtopia.
Pert wasn't as tough, so he'd take longer and build extremely advanced poison-proof suits for his warriors, but follow the same route.
I think Mort would have turned into Hercules on Olympia (like Ferrus Manus) and if he landed on Prospero then there would be no Prosperans left because he just doesn't seem up to the task of helping their psychic problems.>>60485567
Both Fenris and Prospero have psychic influences on the planet.
Russ was encouraging use of the spirit of Fenris or whatever long before he could have known it was benign and if he was on Prospero probably would have gone for sorcery just like Magnus. He could have psychic howled all the warp wasps away to help the people.
The legion wouldn't have had any wolf tones but would still be psychic due to the prosperans affinity.
So you'd have savage, barbarian semi-psychic space Egyptians.
Magnus would have bargained with said Spirit of Fenris in a hope to stabilise mutations, as Wulfen types would probably have been an even bigger problem.
The Fenrisians would have still been wolfy vikings. The legion would have still had mutations and psychic abilities, but now they're even more wolf-themed.
Also Magnus would literally be Odin.
