The place where the light is so strong it burns out color and flesh.While the main danger of The Depths are the monsters that inhabit them first, and the environmental hazard such as darkness second, with the Surface Layers it's the opposite. That doesn't mean the beasts of the Surface aren't dangerous. Many people living deeper than the Surface fear them as many could die once one of them slips to the lower layers. This is one of the reasons why even though they are often seen as weirdos, the People of the Surface, who hunt those beasts, are the reason why The Pit is much safer.
Where the death can come from Above.
Where a step outside means death.
The SunThe most dangerous thing in the Surface Layers is the Sun itself. Its rays are so strong that just underneath the surface they are able to burn someone alive if they don't wear clothes oiled with a special type of protective oils. In the lower layers of the Surface, it is still so strong that it bleaches out the color from the clothes and hair, erodes the buildings and evaporates the water (however, the Water Element can still show up here and materialize as a lake or an oasis.
It seems like there is no night above the Surface.
Fauna & Flora
The animals here have adapted to the harsh environment.
A lot of them has skin modified in a way that it disperses most of the heat from the Sun rays, or they can move through the ground like fish move through the water. Some are completely blind as to not be blinded by the light and others have eyes that can withstand it. The plants grow here very rarely, mostly in the places where there is a constant shadow. It is almost impossible for them to grow elsewhere as the Sun destroys any nutrients there are in the ground. Even if there is a lot of the Nature Element in the air, it will probably manifest as tumbleweeds.
