This Dungeons & Dragons adventure begins in a world of the player's choosing—perhaps a world of you their own creation—then ventures into the Feywild. Also known as the Plane of Faerie, the Feywild is a place of wonder and whimsy ruled by unfettered emotion.
The Feywild is a parallel plane to the Material Plane. Unlike the Material Plane, the Feywild is fueled by wild, magical energy drawn from the emotions of its inhabitants. Because of its connection to the Material Plane, the Feywild has similar topography and geography to the mortal world, though exact locations are constantly shifting and are therefore impossible to plot.
Although the general geography of the Feywild and the Material Plane is similar, the Feywild has a much more primal landscape. Nature rules in the lands of fey. Where you would find sprawling cities in the Material Plane, you might discover only hunting outposts or desolate ruins in the Plane of Faeries. Similarly, locations with patches of wilderness in the mortal realm could be vast, impassable forests in the Feywild.
This raw, primal magic makes the Feywild an extremely dangerous place, even for those who call it home. Adventurers, or those unlucky enough to unwittingly stumble into this land from the Material Plane, must ensure they are not lulled into a sense of complacency by the Feywild’s beauty. The sporadic, magical nature of this land can kill mortals as quickly as any of its dangerous inhabitants.
The Feywild as we know it in D&D fifth edition was first introduced in the fourth edition book Manual of the Planes. This realm of magic and chaos is seen as the spiritual successor to the Plane of Faerie featured in the third edition book Manual of the Planes.
The fourth edition first introduced the idea that eladrin, powerful elf-like beings that make up a large portion of the plane’s population, originated in the Feywild rather than the Plane of Arborea as discussed in previous editions. The fifth edition supplement Mordenkainen's Tome of Foes has expanded on this sentiment, stating that eladrin are elves that might be native to the Feywild, or were at least exposed to the presence of the Feywild for more than a century.
Due to the Feywild’s close relationship with the Material Plane, crossing between the two is considered so easy that it is sometimes done by accident.
Fey crossings — areas where the two planes converge — can be found in ruins and old forests, often changing locations based on the weather, alignment of the planets, or time of year. These portals are random enough that unwitting travelers can stumble across the barrier between the realms by being in the wrong place at the wrong time. By the time the hapless traveler realizes that something is amiss, the portal might disappear, not to return for an hour, a day, or a century.
While the random convergences of the planes are dangerous and chaotic, there are areas that act as permanent fey crossings for the purpose of intentional travel between the Material Plane and the Feywild. These crossings are usually well-guarded secrets, as the fey don’t want just anybody to be given carte blanche access to the powerful magics that reside in the land of faeries.
If your players are looking for access to the Feywild, they may seek out assistance. For instance, they could navigate a treacherous swamp and bargain with a hag for the knowledge, or protect a patch of wilderness against an industrious noble for a druid who knows the fey’s secrets.
Whether travelers arrive intentionally or by accident, the chaotic Plane of Faeries does not show favor or mercy. The Feywild is deadly, there are no two ways around it. Because the Feywild has few civilized areas and the roads between them are unpredictable, traveling from one part of the Feywild to another is dangerous. Adventurers looking to move between cities in the Feywild might have to cross through swamps full of poisonous gas or forests that attempt to trap travelers in a never-ending maze.
Even if visitors from the Material Plane manage to survive the untamed wilderness, innumerable deadly creatures call the Plane of Faeries home. Because the magic that shapes the Feywild is more chaotic and powerful than the Material Plane, even its most common creatures can be infused with power that can rival hardened adventurers.
Thus, those who journey to the Feywild — whether on purpose or by chance — must tread carefully, for even the most innocuous-looking clearing or creature could lead to their end.
The Feywild, often called the Plane of Faerie, is a vibrant, unrestrained echo of the Material Plane. If the mortal world is a painting, the Feywild is that same painting rendered in blindingly bright, oversaturated colors, where the brushstrokes are alive and the canvas itself breathes. It is a realm of absolute emotion, primal nature, and wild, unchained magic.
A Landscape of Exaggeration
To walk in the Feywild is to be overwhelmed by sensory input. The flora is gargantuan; ancient trees scrape the sky, their trunks wide enough to house entire villages, while flowers the size of wagons bloom with bioluminescent light. The sky is locked in a perpetual twilight—a breathtaking blend of violet, gold, and crimson—as the sun permanently rests just above the horizon.
The plane naturally defies rigid cartography. It is a world without hard boundaries or static grids, where paths are dictated by emotion, intention, and the shifting of the seasons rather than fixed geometry. A familiar mountain range in the mortal world might be reflected here as a chain of floating, crystalline islands, while a sprawling mortal city might mirror as a labyrinth of towering, ancient briars.
The Courts and Inhabitants
The Feywild is home to creatures of myth and folklore. It is ruled by the Archfey, god-like beings of immense power who embody different aspects of nature and emotion. They generally divide themselves into two primary factions:
The Seelie Court: Governed by Queen Titania, this court embodies the warmth of spring and summer. They are often viewed as benevolent, though their whims can be just as destructive to mortals as a raging summer wildfire.
The Unseelie Court: Ruled by the Queen of Air and Darkness, this court represents the chill of autumn and winter. They embrace the macabre, the predatory, and the sorrowful aspects of the natural world.
This realm is the ancestral home of the Eladrin. These fey elves are deeply attuned to the plane's magic, their very appearances and temperaments shifting in tandem with the seasons. Alongside the Eladrin, the plane teems with satyrs, sprites, hags, blink dogs, and more sinister predators that stalk the shadows of the towering canopy.
Beneath the surface lies the Feydark, a subterranean mirror of the mortal Underdark. Instead of oppressive blackness, it is a riot of glowing fungi, crystal grottos, and deep-earth magic, inhabited by Fomorians and twilight-warped beasts.
The Rules of the Realm
Mortals who wander into the Feywild must navigate a society bound by ancient, alien laws.
The Rule of Words: Names have absolute power. Telling a fey your true name can give them dominion over you.
The Rule of Hospitality: Guests and hosts are bound by strict codes of conduct. Breaking bread in a fey's home secures temporary safety, but a breach of etiquette can result in eternal servitude.
The Rule of Reciprocity: Nothing is given for free. Every gift demands a favor in return, and fey bargains are magically binding, often twisting the mortal's intent into a cruel irony.
Time and Memory
Perhaps the most dangerous aspect of the Feywild is its mutable relationship with time. A traveler might spend a single enchanted evening at a Seelie revel, only to return to the Material Plane and find that a century has passed in their absence. Conversely, months of agonizing survival in the wild might equate to mere minutes back home.
Worse still is the plane's grip on the mind. Upon leaving the Feywild, a profound, magical lethargy of memory often sets in. Without a strong will, a mortal might forget their entire journey, left only with the lingering, dreamlike feeling of a beautiful and terrifying world they can no longer fully recall.
