Smaragd

Smaragd, a realm of ever-shifting colors, is a radiant emerald jungle of heal, acid rain, and fermenting poisons. The jungle floor is difficult to find, as the forest has as many as seven canopies in places. Many who venture to this part of the multiverse claim that the layer has no jungle floor at all, just layer after layer of darker and dimmer canopies. While untrue, the jungles of Smaragd are much taller than any jungles on the Material Plane, comprising seven canopies of deadly fauna and flora. The jungle floor is a swampy mass of rotting vegetation, acid pools, and poisonous clouds. 
The jungle is the home of Merrshaulk, god of the yuan-ti, as well as many roving tribes of barlgura. Merrshaulk slumbers in a vast set of snake-infested pils and caverns, and is uninterested in being roused from his slumber by anything less than a direct threat. Most who intrude on his caverns are simply devoured; the rest survive only because of the power's all-consuming sloth.
Ramenos, the god of the bullywugs, also sleeps in a realm within Smaragd, though his resting place is an enormous hollow tree. His tanar'ri followers call him the Sleeping God, and offer him sacrifices by placing them within his perpetually open mouth. Other than the vipers, boas, pythons, venomous toads, and acidic rains, Smaragd is a relatively quiet and benign layer of the Abyss. Its dangers are passive rather than active.
