The shout that Vol gave, he didn't understand a word of it. It was a deep, and guttural sound, the sort that a witch doctor might whisper into the flames, in order to secure a deal with the devil. And for the very reason that he could not understand it, and after witnessing what he had witnessed, it struck Fieldcarer with an overwhelming degree of power.
He felt his blood run hot, and his temperature spike. He'd witnessed something impossible, and like all men that had witnessed a God in person, he felt the urge to kneel, or pay salute. He raised his sword high into the air, and bellowed back the word he thought he heard, with all the emotion he had in him. "KURVVSAKK!!" He roared, hoping that word would grant him strength, just as it had granted it to Vol.
What he did not expect was for the entirety of the army, some six hundred men strong, to echo that cry along with him.
