speculations with the plot and characters
in my evidence to prove this that other people in the game have similare traits (possibly the same) with other factions in darksiders the angels for example they are wearing gold on their armor which is the angels as described in james swallow's Heart of rage.
As with sameal who has some similarities to the daemons
strife, death, and fury are almost identicle to the Tau's, Necron's, and the space elves.
It is most likely that War will be the god emperor that is worshiped by the Imperium of man and the Imperium of man are really nephilim decendents taking the title of man and women and becoming new kind of humans
meaning that War will be fighting alone after all
