Abyssal Layer
The Abyssal layer is the ground level of the Green Maw forest biome. The halfling population here is the smallest of any biome, and most residents are salt miners. Brachiation is only possible from vines and roots tunneling from the Twilight layer into the Abyss' vertical boundaries. Cloudscraper trees often have stairs built from their Twilight layers down to the Abyss.
The world of the Abyss is nocturnal. Some streams of gloomy light filter through holes in the Twilight layer's ground level. Light at the soil level of the Abyss is almost always bioluminescent. The ground is uneven and thick with fungi, decomposing collapsed trees, caves of gnarled roots, and towering tree trunks of all diameters.
Most trees of the Green Maw have their roots in the ground of the Abyssal layer, but vary in how they get their roots there. Some drop seeds in holes along the Twilight layer's floor level. Some grow an initial root system in the Twilight layer and then patiently grow permanent roots that penetrate the Twilight's floor and dangle farther and farther down until at last reaching the Abyss's soil. Still other trees establish themselves in the Twilight but then grow heavier and heavier crashing down into the Abyss.
An example of a tree that grows solely in the Abyss is the Balefire.
