Undying Army.
The battles raged on like an endless bonfire.
Blood was spilt, flesh was rend asunder, and bones were turned to dust.
Still, no matter how badly the Lightslayers were torn apart, in just a few seconds, they managed to rise back to their feet, their body slowly mending together, and their eyes shining with deep seated insanity and piety.
They gladly shed their blood, gladly reached the threshold of death over and over again, just to rise back up like a horde of undying zombies.
Solely because of this, they were able to keep the Mutant Horde at bay, relentlessly pushing them back.
Still, although they couldn't die, this didn't mean they felt no pain. Despite 5he many attempts to dull the pain, losing oneself to pain, something that was a fundamental part of the human physiology was all to easy.
The minds of humans was weak. And the continued pushing of this line could lead to irreparable consequences.
