My army is falling to pieces, their morale is broken, they refuse to fight.
I imagine it's some kind of Alexander thing, weeping for there were no more worlds to conquer.
They face the continuously spawning demon armies so demoralized. Sure, for the first time since the fall of Sarkoris the demons have been driven all the way back to Threshold, sure Khorramzadeh and his armies have been defeated (congratulations on actually getting that to work in the latest patch, and dope reward for it too) but without any more forts to take is life even worth living?
My troops certainly don't think so.
