You are a special kind of species. You are no different from an above-ground species...but with one catch. You evolved below the earth, where there is no sun and plenty of minerals. Feeding off of other creatures, your underground species has grown to sapience. Now, you must work with your limits of the ground and your aversion to the sun to grow and, eventually, conquer the surface and beyond.
