Mortarian is such a loser.
-The Emperor finishes his foster father, seethes about it for 10,000 years
-"Hates tyrants" but does nothing to free the people and only commits heinous war crimes
-Also still takes orders like a good dog instead of doing his own thing like the White Scars
-Throws a temper tantrum about the Librarius so big the Emperor has to hold a big council about it (not even Russ whined this much)
-Despite getting what he wanted he still turns against the emperor
-Gets rejected by Garro, seethes about it for 10,000 years
-Realizes his side is warp infested, does nothing about it but whining to Jaghatai
-Gets rejected by Jaghatai and fights him to a draw, seethes about it even though he once said "we were made for different fights"
-Starts getting into warp juju himself and becomes addicted to it like it's meth
-Typhon commits multiple acts of insubordination, but he does absolutely nothing about it
-Still trusts Typhon after this and gets sent to Nurgle's outhouse
-Gives in to Nurgle instead of taking his eternal punishment like a real man
-Becomes a disgusting bloated moth, can't seethe about it because he's now a slave
-Gets a rematch with Jaghatai, still can't win because he can't stop seething
-Gets banished by Garro so hard he's never seen again until 10,000 years later
-Still can't control Typhon (now Typhus) by the way
-Seethes about Gulliman for 10,000 years for some reason
-Ignores Abbadon's plans and heads to ultramar where he loses so hard that Nurgle focuses his near omnipotent attention solely just to spank him
-Has never had a clean win against another primarch, has won no major wars by himself, and has never had any redeeming qualities pre nor post-heresy
-Really ugly
And all he can say is "I will endure."
Apparently they can get married and faith is good to have, they’re fit and honor oaths, all very desirable qualities.
So yes, I would help refill the Imperial Guard.
Sorry guardsmen that's what those Pink and Black marines over there are for. Weird chapter, I wonder where they are from?
