The Great Abyss

The great abyss is a geographic feature that consist in a seemengly bottomless chasm. Originally not part of this world, the great chasm first appeared during the great glaciation between the Valderian empire and the Luminesian empire. At first it appearead as large cracks in the terrain like if the world was going to be tear open in two parts. With time these cracks became increasingly larger at the point of forming a large hole that completely separated the continent. The great abyss is mostly impossible to pass as the distance between the two edges is too long and it is too deep and steep to attent any descent into it. Some locations, though, are still close enough so that it was possible to build some bridges, however few people would attempt to cross the abyss as it would be extremely dangerous.
There are many myths sourrounding the formation of the great abyss, the most accreditated is that the element of darkness is affecting the world and created an hostile environment for any living form. It is believed that at the bottom of the chasm there are the creature of dakrness that from time to time rise from the abyss attempting to conquer the surface and destroy the world.

Ecosystem

At the bottom of the great abyss there is an unbreathable atmosphere and any living creature would quickly die without appropriate equipment or magic powers. Because the bottom is closest to the center of the world the temperature is extremely high and there is lava flowing at every corner. On the surface, near the edges of the abyss there is only bare terrains and extremely cold temperatures, when people go too near the abyss they have a deep feelings of unrest and generally they try to avoid going there.
