Space Wolves lost time playing masscre on Prospero, Ultramarines were far away fighting a useless war, Half dark angels betreyed the emperor and the primarch lie in stasis under their keep (hemhem cow..rd), ONLY THE BLOOD ANGELS were on the side of the emperor defending the Holy Terra; Sangunius broke the bones of a Deamon on the door of the Golden Palace and sacrifice is life in the battle with the Archenemy, so WE ARE THE BEST
Not half , about 10 - 20% or less. Number is still unknown. DA is probably the only who can reject Dark Gods and return to Emperor's light ( ex. Luther) Primarch was taken by Watchers in the Dark. In Statis is Luther. BTW By now background Lion in anger can easly kill Greater Deamons ... KILL not cast in the warp.
It'd be nice if some chapters that won't be in the game are given some character to represent them, e.g a Celestial Lion could be seen wandering about the Black Templars area.
Actually no, Luther is in a Cell and still alive, Chaplains regularly try to make him repent and also go to tell him of Fallen Angels that have repented The Primarch is lower in the Rock in Stasis with the Watchers and only the Chapter Master has access to his chamber
The final secret known only to a very select few is that, buried even deeper within the Rock than Luther, Jonson lies sleeping, waiting with the Watchers in the Dark for the time when he will be needed again, to lead the Dark Angels in a new and greater crusade. Save the Watchers in the Dark, only the Emperor knows of this secret[1][13] http://wh40k.lexicanum.com/wiki/Lion_El'Jonson#The_Fate_of_Jonson
Since the Raven Guard are not included, man that would be cool. I have to go with Blood Angels. Jump Packs!
it's from old codex. In new there is only one hint about Lions fate. page 18 -over and over again he repeats that he has no need of repentance or confession, for one day Lion El'Jonson will return and absolve him of his sins. He claims that day is near and that can feel the Lion is already close at hand.. new back
went with Ultramarines. personally much more a fan of the sons of Dorn and Salamanders but alas none of them will be in the game(yet)
