Fengali forest

The Fengali Forest is a large patch of drowned flora bordering the Western Seas and approximately 100 miles off the coastline of the Steadfast.

Background
The Fengali Forest is composed of roughly 4,000 acres of mostly underwater trees, many of which consist of evergreens, water tupelos, and longbow willows, with their tops rising up to 20 ft. from the water's surface. Branches thread out like trunked lilies with giant vines covered in poisonous barbs lining them like snakes. Meanwhile, from deep below, the roots of all these trees connect to one another in a tangled mass of ever-expanding roots. These lilies will annually produce nests of orange scented flowers, whose consumption will quickly result in death. Additionally, more of the flowers will cocoon themselves inside the victims body until they're ready to sprout. They've also been known to swim as far as a hundred miles in order to return to their original nesting grounds.

A tight clan of humans or "grovers" as they're known live among the branches and trunks of the trees within the Fengali Forest via a series of floating shacks and platforms. They construct them from scavenged synth and metal parts that drift in from the ocean. Normally, the grovers are never aggressive towards outsiders, though they will change that attitude whenever they or their home is ever under threat. When provoked, grovers will use the vines of the Fengali Forest as whips or even lassos against their foes, as they have since become immune to their poison. About a half a mile below them lies a root system not unlike a series of coral reefs filled with deep sea creatures and treasures, such as the numenera. The most aggressive of these underwater denizens is what's known as the root shark, a quick solitary hunter that will lie in wait camouflaged among the roots or sea bed until their prey draws near. Another notable species are ghost crabs, who've been known to grow as big as 5 ft. in width. Ghost crabs are best known for crafting intricate webs of silica between roots and have been known to also appear and disappear at will, hence their name. Blind, the ghost crabs heavily rely on their honed senses of touch to take down their prey, having become so skilled enough to give even the root sharks reason to distance themselves.

Lastly, 3 great ocean rifts flowing parallel to one another throughout the Forest's sea bed, each one a mile wide and 3 times as deep, it's here that brave explorers may find the most valuable of items as well as the most deadly of resident undersea fauna.
