THE CITY OF DARKNESS
Many years ago - some people say 500, others say 5.000... but maybe even only 50 - the current lands, now known as 'Exiled Lands', were full of life.
A huge and such city, now called 'The Unnamed City' or 'City of Darkness' was one of the richest cities in the world.
But as always, when someone grows strong and wealthy, the neighbors start to become envious and start to act against the city. First hidden, but when they found out, that it doesn't work, they openly declared them as enemies because they would conspire with dark gods.
The war lasts for many years, and the former rich and proud city was soon totally isolated and the people living there began to suffer.
Ironically, that was the reason, why the Lord of the City - a strong and kind man named Leroc Gerna - decides to really make a pact with a demon.
The demon - Retarazul - promised to fight everybody back, who holds the city under siege.
And he kept his word... Armies of demons, undead and other dark creatures entered the world through portals in the city, now officially invited to this world... They killed everybody around the city, and depending on what kind of monster raged in the area, after it there were only desert, ice or fire.
They kept their promise, but they never promised to leave as soon as it was done.
To defend the rest of the world the nations around the city called for their best priests and mages. All of them worked together and were able to build up a magical barrier, that keeps everybody inside.
The city and the surrounding land were lost...
BEHIND THE WALL
But not everybody behind the Wall died... Some human survived and hide into caves or other places the creatures now controlling the city couldn't find.
Over the years, something like a balance was found. The demons and other dark creatures stayed in the city ruins. Many of them went back to their realm but some stayed. Some other races were brought as slaves to these lands and some of them were able to flee or were freed.
The remaining humans learned how to fight the creatures - about their weaknesses and different factions with different ways to fight the threads were formed. Many of them followed the old gods - at least in their own way.
Now... So many years later... There is still the old war, and everybody who comes to close to the 'City of Darkness' is attacked and finally killed or enslaved by these creatures...
Is there a way to push them back? To defeat them? Close the portals and leave these lands into a life in peace?
