*the lone old man was sick, he was coughing up blood and trembling in his speech, barely could walk at all.
As you seemingly have purged the galaxy of a deformed sick mutant(
must have been Nurgle - let me guess: He was passive, but hard to kill. After touching him, your body would be marked with Chaos), the Great Emperor considered to forgive your soul.
He finally rewarded you with the highest honor a man could wish for:
By mercily freeing your soul of your polluted weak body and endowing you with a glorious death in battle in His name.
Your animus will contribute and be assimilated by his immeasurable intellect.
Sorry man, i got brainwashed by warhammer 40k when i was a kid
My cryptic bullshit redundantly(as Buoidda already pointed out) tries to say that the buildings have to be taken down. But i dont see a bug since i guess it is intentional.
I think its not a big deal for dev's, because the game is just not meant to reward players, who slaughter whole villages, with immersion...
Maybe i gave you some, although obviously stupid lore. Would be funny to write a text like that into the graveyard.
It is like with many suggestions and complaints from our side: they got probably bigger stuff in mind...
Actually, thinking about it, i would consider it possible that the "taken-stain" could be some part of the spirit-karma mechanics.
