The Abyss is a harsh, cruel, and vile land. It is the worst place to live in, quite literally. Not a single plant can live in the Abyss, for the environment is too toxic, unfit for any flora. Since its inception, not a single plant has managed to grow. Many have tried, none have succeeded.
The only food found in the abyss is demonic beasts and demons; some elven scholars argue that there is hardly a difference between the two. The Abyss is a harsh place; none in the entire universe comes close.
It can give birth to life, but it cannot sustain it. Every three years, certain layers in the abyss turn into brood hives, the ground splits open, and many larvae, numbering in the millions, on a single layer emerge.
These larvae are of many shapes and sizes, but one common thing about them is the white skin and the sharp teeth that line their mouth. And what happens when they emerge from the ground?
They eat, eat, and eat.
