I'll elaborate a bit on my take on the feywild. Within the feywild is an area known as the Path, or the Druid's Path. This is a route through the forest that only druids know, leading to their secret grove. Various druid circles each have their own grove somewhere within the feywild, and most only visit there to appear somewhere else (travel through plants), or to meet with other members of their circle. Few ever venture further into the feywild, for it is a dangerous and sacred place where humans are usually not welcome.
Those who venture further into the Feywild, can encounter any of the following areas:
The Forest Heart
The Forest Heart is a location deep within the forest known only to some druids, witches and fey. It is a pocket dimension found deep within The Path, and the home of the Lord of the Forest. It resembles a massive clearing under a canopy of leafs, shrouded in a dim blue light. Faint light-blue light leaks through the green roof up above, creating a dancing pattern of light spots on the forest floor. A small lake surrounds an island with a gigantic white tree on it. Surrounding the clearing are mossy stones covered in old crooked trees. A slanted cave lurks to the west, with ghostly whispers emanating from within. A series of waterfalls are just to the east, with another cave clearly visible behind them. Lights dance around the clearing and fairies and other fey-folk can be seen enjoying the peace and protection of the heart. The soft jingle of little bells can be heard occasionally, though the origin of the sound is unknown. Three paths lead towards this grand clearing, with one being shrouded in twilight.
Iridescent Lake
Various small streams lead up to this lake. No fish seem to live in this water, but drinking the water acts like a fountain of youth, although for only a few hours. Surrounding the lake are plants and trees shaped like humans, which are all former druids and witches, who chose to become one with the forest.
The Lord of the Forest
This large white stag is the guardian spirit of the forest. It has huge antlers that seem made of tree branches, and are covered in butterflies. He walks across water without even breaking the surface and glows with a bright white light. He is neutral good and can speak telepathically. When he speaks, he speaks with a male and female voice simultaneously. The Lord of the Forest has a memory that goes back many centuries, as he is the tree and the deer is but his avatar. The Lord of the Forest can see into the past and future, and if he chooses to show himself to you, can be a great source of advise. As he is a friendly being, he will warn mortals of the dangers in this realm.
Fairy Falls
Six waterfalls cascade down mossy rocks into a small pool where fairies bathe. A gentle stream leads the water to the central lake of the clearing. The fairies are nude and vanish when approached by mortals, as they are very shy. But just because you can't see them, does not mean they are gone. A small path leads up towards one of the waterfalls and to another cave. Reaching the cave requires traversing slippery rocks.
The Whispering Cave
Mossy stones lie stacked on top of each other on a slanted slope. Trees grow on top of the stones, their roots twisting their way down to the forest floor. Beneath the rocks a small path leads into a dark and ominous looking cave. Familiar ghostly whispers emanate from within. It is very dark inside the Whispering Cave... too dark to see anything without a light source. The cave leads downward, and the rocky moss covered ground can sometimes be slippery and treacherous.
Deep within the cave is a room with a slab of obsidian in the center. The black obsidian is slightly cracked and semi-transparent. Anyone who steps onto the obsidian will see thin colored lines appear from where they are standing, and stretch to a couple of glowing standing stones. These standing stones are made from obsidian also. They are about half the height of a grown man, and are unevenly spaced out. Some are closer to the center while others are much further away to the back of the cave. Voices emanates from most of the stones and blurry images can be seen inside. These stones can be touched, listened to, or looked at to receive visions. These visions show people connected to you; friends, family, adversaries...
Ancestral Caves
These caves are the remnants of ancient tribes of druids. They are covered in cave paintings showing how the earliest druids took human children to raise them in the wild. It also shows how some druids made the ultimate sacrifice and turned themselves into trees. Bowls and urns are scattered about, containing the remnants of paint. On the ground is a strange spiraling symbol carved into the stone. It seems to have been used for calculating celestial configurations. Stones are placed on very deliberate spots on the symbol, marking the locations of planets and stars.
The Lonely Hut
Above the waterfall is a strange tree with a little hut between its branches. The tree leans over the side of the cliff. There does not seem to be any normal means to climb up to it. The hut is made from woven branches and dried wheat. The hut is home to the Forest Oracle, who is the last remaining druid chosen to watch over the Forest Heart.
Grave
Near the lake is a grave surrounded by white flowers. A stone slab lies on the ground with illegible writing. A stone statue of a lady overgrown with plants stands where a headstone would be. The grave belongs to the previous Forest Oracle, who was slain by enemies of the forest.
Stone Heads
These giant heads seem carved out of large rocks and are covered in moss. Their eyes can move slowly and they can talk. They were carved long ago by the fey that live here, who gave them a face and the ability to talk. The stone heads are friendly towards humans, as they have been among druids for many years. The Stone Heads adore everything that grows around and on top of them. They know much about the surrounding area, as theirs are the memories of ages.
Stone Circle
This circle of large stacked stones resembles stonehenge. There is a small clay bowl on the central stones and many flowers grow around the circle. Into each of the six standing stones a different swirling symbol has been carved, the meaning of which is unclear. The circle radiates magical energy.
Dais
A crumbling stone staircase leads up to a stone dais; a round platform with strange swirling lines carved into it. The dais provides a good overview of the forest clearing. In ancient times this dais could open up, revealing a path into the caverns below the forest. The knowledge to open it however is long lost. Six circles are engraved on the dais, each with a unique symbol also found on the standing stones of the stone circle. Each circle demands a natural element for it to activate.
The Heart Tree
This massive white tree dominates the clearing. Its thick roots cover the small island in the center of the lake, and dive into its water, only to emerge on the other side. They cover the forest floor of the clearing in every direction. In the center of the tree is a large vertical opening; a dark crack that leads further into a system of tunnels inside the tree. Each tunnel leads to another fey realm. The tree’s branches are covered in blue lights from fairies. Inside the tree the sound of a beating heart can be heard, because the tree is literally the beating heart of the forest. The tree has countless tunnels inside of it, all leading to small pocket realms. Navigating the tunnels can be difficult, and it is easy to get lost and end up somewhere you did not intend. But those who know how to navigate its winding tunnels, can travel to other realms of the Feywild.
The Illumine Crown
Deep inside the Heart Tree, a tall shaft leads upward to the top of the tree. Up above is a crown of lights where countless fairies swarm around a large hive. Strange sweet nectar gathers in pools surrounding the hive. Drinking this strange fluid brings a person into a strange trance where they can see the future. Branches can be climbed to reach the very top of the Heart Tree, where you can gaze across an endless forest beneath a pitchblack starless sky.
The Forest of Faces
Surrounding the Heart of the Forest is an endless forest called the Forest of Faces. The trees of this forest are covered in many haunting faces. The trees are sentient and hostile to intruders. Beneath their roots are many smaller hearts of other forests in the world.
The Weaver Domain
A system of webbed tunnels, where Queen Dantomere reigns. This realm connects to the Twilight Vale and the Mirror Realm. The spider queen watches over the Loom of Creation, where her fate spinners build connections to other worlds.
Queen Dantomere
A spider queen who lives inside the Heart Tree. This gigantic spider lives inside a system of tunnels where she is tended to by her spider servants. Queen Dantomere is true neutral, and views life as a matter of eat or be eaten. She has a tendency to use webs and other spider related words in her speech to explain her thoughts. She also speaks much of weaving, shedding, picking and battening. The spider queen is completely ammoral, and does not have a sense of right or wrong, she respects only survival. She and her minions will not be hostile to visitors however, though she talks gleefully that her visitors could be blessed by becoming food for her, and becoming part of the eternal circle of life and death. She even promises them a nice view when they are cocooned in her chamber, if they volunteer to be food. The spider queen can be a powerful ally or enemy, depending on how she is treated, and whether her children are attacked. She maintains the connections between dimensions and knows much about gateways to other worlds.
The Twilight Vale
A creepy looking path leads into the oldest part of the forest. The path is crooked and muddy. Branches and roots seem to constantly be in the way, trying to trip intruders. The air is fetid and sickening. Strange flowers and mushrooms grow here. Ghostly child-like voices can be heard all around; the voices of unseelie fairies. This forest is full of strange looking colorful plants, many of which are very poisonous and/or hostile. This forest is home to evil fey, who can be quite dangerous to human intruders. The Twilight Vale harbors the anger of all forests and fey. Dead leafs rain from the treetops of a forest that is shrouded in permanent twilight. Hundreds of eyes watch from every hole and crevice with malice and hatred. This area connects to the Weaver Domain and Shadow Realm.
The Shadow Realm
The entrance to this realm is a gateway of pure darkness. Strange echoes emanate from within. The realm itself resembles a distorted version of the topside world, where everything looks like shadowy silhouettes. All sound sounds as if it is underwater; dampened and muffled. A shadowy shape watches any visitors with great curiosity. This realm connects to the Twilight Vale. The shadows here are most interested in life outside their realm and would gladly switch places with mortal visitors.
The Lord of Shadows
This shadowy figure assumes the silhouette and voice of someone you are familiar with, and who has visited the shadow realm before. He has all of that persons knowledge and memories, but none of their emotions and feelings. The shadow figure cares about his host body, the one who walks the world of light, and knows that his host cares about his friends. Therefor, he understands that his host would like for him to assist those who are dear to his host, depite not sharing any such feelings himself. When people traverse the shadow realm, a shadow takes their place in the world of light. There for he is one of many. Time moves slower in the shadow realm, allowing a person with a physical body to seemingly jump instantly from one place to another.
The Mirror Dimension
The entrance to this realm is a massive mirror that stands at the end of a tunnel, supported by a wooden frame with carved wooden legs that can move. Above the mirror is a wooden face shaped like a lion, that roars in the distance. The mirror itself casts a purple light into the tunnel and its surface is made of a purple crystal.
Beyond the surface of the mirror a strange world can be seen with floating crystal platforms, glass shards and many more mirrors. Many people get lost inside the realm as it is very disorienting, and are often never seen again. This area connects to the Weaver Domain.
Gem
A girl often found within the Mirror Dimension. This 10 year old girl is gifted with powerful magic but does not understand her powers. She also seems heavily autistic and often uses her magic by accident. The mirror realm is a world she traverses often, despite it being very dangerous to do so. Gem often talks to inanimate objects, such as rocks, who are her friends.
Palewood Copse
A path surrounded by dead trees and plants, leads to the forest of dead trees known as Palewood Copse. The path is foggy and the air is cold and moist. It is completely quiet in this part of the forest. Strange ghostly vapors fly through the fog, pulling at the clothes of intruders and sounding ghostly cries. Not even spiders dare to venture here. The Palewood is where the spirits of deceased fey go before they are reborn. Will ‘o Wisps try to lure intruders further into the woods so they get lost. The fey refer to them as corpse lights. The Palewood is home to undead fey, showing that undeath is not always unnatural. A dangerous environmental effect of the copse is forgetting where you came from and why you are there. The forest messes with a person’s mind, altering their memories and their perception of time. This area also connects to the Twilight Vale.
