Perseverance

The walls groaned and moaned as the enemy encroached on the defenses of the bastion. The men and women manning the walls and defensive turrets as well as great siege weapons appropriated for defense of the bastion. 

Creatures of any and all kinds spawn from the darkness pushed on. 

The deaths of their brethren completely ignored by them, as morality is a completely foreign concept to them. As they are nothing more than beasts, nay... less than beasts. For beast's have at least some semblance of self-preservation, as well as follow the rules of nature. The only way to describe the encroaching horde is comparable to a force of nature, but it is not, for it is something completely unnatural. 

But the warriors of the bastion held, as they had for fortnight, waiting for the dawn to finally arrive in this desolate artic, tirelessly against the horde. They could be easily comparable to daemons, but even daemons would have some resemblance to reason, these creatures, do not.

 Bolt after bolt was fired, trebuchet after trebuchet, flaming boulder after flaming boulder, arrow after flaming arrow, yet the tide of malevolence continued strong, yet they still held on, even if their brothers and sisters fell from projectiles of the enemy attempting to breach through, they still held, their wills unbreakable, their determination unwavering, as their preservation for the future holds true. 

Soon, the bending of the walls slowly ceased. The creatures soon began to flee as the locust on life they are. And in the distance, the first light of dawn in 6 moons has arrived. The first step against the darkness, has finally paved into a reality.
