Watcher's Keep

History
There are two types of walls in this world: walls build to keep dangers out, walls built to keep dangers in, and some that serve both purposes. The mighty keep stands atop a suspicious mountain in the middle of the sea, and while some say it is magical, no actual magical properties have been found upon inspection. The outer ring of the wall was built in the shape of a star to ensure no one could approach without getting shot, for the inner ring held down an even greater evil than mankind. The Void and its inhabitants cracked the foundation of the world and had spewed out centuries ago, but now the cracks are mostly dormant, leaving only the echoing screams of battles past. At the center of the keep is a pitfall, where the Sethris Night Guard have sealed the walls from the deepest points to the entrance to the main tower, forcing any creature of the dark to climb up and over brick and glass, an arduous process for even the best climbers, right into the blades and shields of people determined to keep the nightmares of the past inside.

The Void was first discovered to humanity when the Mekanika ousted The Void Dragon; casting it into the earth and leaving him there. Many years passed and one day the earth cracked. No one was expecting the attack as a great earthquake shook the earth, breaking the plains and turning them into mountains. Then the night set in, and as black dragons flew over the sky, it was blackened by their toxic smoke. Creatures unknown began consuming the population, and nothing that drew breath would see tomorrow. This happened somewhere around 52 years ago in a land far away, and it will happen again in the land of Eldham.

The first Void Army was defeated after a massive chunk of it was slaughtered by the Thirteenth Warforged Legion, and two thirds of the void were already dead when the armies of humanity decided to finally join in the battle, but it was too late for their children of war, as most of them died in the battle and the ones left were put out of their misery as per the persecution laws at that time. The gods had other plans for one of those children, as he lived, being sent flying by an enemy and slamming into a tree from a forest a few tens of meters away alongside his century commander that died shortly after hitting the ground.

Now this child of war guards the "Wound of the Earth", as he refers to it, with his very being. He jumps deep into the abyss to help the earth heal with rituals that help his kin when they were wounded while fending off whatever creature decides to meet him in battle. He calls himself "Daos, the Void Keeper", and the sacrifice he makes keeps the void at bay and the terrors of the dark under control is absolute, as the void corrupts those who listen or look too closely.

This Fortress stands outside Avaris, into the nearby sea where most travelers would not search for cities, and where treasure seekers might be discouraged to look, for when they try to enter they excite the void and make its creatures howl ever so louder in hopes of one day ravaging the land.
