Stoick: "Out there, beyond the sunset, lies the home of the dragons. Legends tell of ships that sailed too close to it, only to drop off the edge of the world, never to be seen again. But those sailors who turned back told tales of a great waterfall and dragons guarding the entrance to a Hidden World."
Hiccup: "Whoa."
Stoick: "Not just a nest, Hiccup, but a land from which all dragons come."[src]
  — Stoick telling Hiccup about the Hidden World  

The Hidden World is the major and titular location of How to Train Your Dragon: The Hidden World. It is the ancestral home of all dragons.

Official Description[]

The Hidden World is an old sea-faring legend about a land at the edge of the world, where many sailors have lost their ships — never to be seen again. Those who have returned reported sightings of a great waterfall and dragons guarding the entrance to a hidden world beneath the sea. A land from which all dragons hail. [src]

Development[]

We wanted something that transcended the idea of a cave. Part of that was delving into bioluminescence and was of channeling light into this subterranean space with the use of crystals that could carry light from magma. We wanted it to be an exotic world that still feels like it belongs here on earth. But it's still a place for dragons and not for humans. [src]

Geography[]

Hidden World

The caldera entrance to the Hidden World in the sea of the Barbaric Archipelago.

The Hidden World is set within a massive volcanic caldera, which serves as a portal to an endless maze of chambers and volcanic tubes that wind their way around the world.[1] This subterranean world is filled with bioluminescent fungi, coral, and bright, scintillating crystals that adorn the vast cavernous spaces and antechambers.[1] Water seeps through cracks in the earth's crust to form waterfalls and collects in pools on coral shelves. Water that reaches the caldera's floor is heated by magma and turned into steam, creating a tropical environment.

Kullersen Fissure

The newly formed Kullersen Fissure in North America.

A new entrance to the Hidden World was created in the twenty-first century when a massive comet passed through Earth's atmosphere, causing an enormous geologic rift known as the Kullersen Fissure on the North American continent. The Fissure is home to a number of interconnected cave systems, some of which lead to the Hidden World's "Crystal Realm" section.

Mushroom Forest[]

After a dragon has entered the Hidden World through the Caldera they get access to a network of caves deep in the crust of the earth. After a dragon flies through this network they reach the Mushroom Forest, where the Hidden World's bioluminescence is revealed. The Mushroom Forest mainly gives home to many stalactites and stalagmites that are completely overgrown with various sorts of mushrooms.

In the darkest depths lies the unknown and it is up to Vikings to explore it! Very few Vikings have been valiant enough to venture into its depths, but those few who have get to witness the light and bioluminescent found within. As dragons seem to take a shine to these underground caves and brightly glow throughout them. [src]

Hidden World Caverns[]

After the discovery of Hobgobblers, Vikings have been fascinated in learning more of these incredible dragons that has led many to visit their beautiful home. Hobgobblers appear to be small, fierce, powerful dragons but they are rather mischievous in their own way, perfectly resembling the area in which they live; full of mystery and hidden surprises!

Vikings can expect these inner caves of the Hidden World to be composed of massive crystal-like structures and have numerous corals running along the open tunnels and like the Annex, a unique touch of gleaming lights can be seen all around. Vikings venturing inside will be left amazed as they watch their dragon light up inside the tunnels. It is indeed as astonishing as it sounds and perhaps that is the reason why these dragons seem to have kept the caverns hidden away from Vikings for quite a while. The caves are full of hidden mazes and tunnels that are sure to test the clever mind of a Viking, and once inside the area reveals beauty unlike anything we've seen before!

Dragons: The Nine Realms[]

Crystal Realm[]

DC-282-Hidden World

The Crystal Realm is the first section of the Hidden World that appears to be located beneath the North American continent. When the Kullersen Fissure was opened in the twenty-first century, it opened a direct path to the Crystal Realm, which is easily accessible via various smaller caves within the Fissure.

As the name implies, this realm contains many large and intricate crystalline structures connected by a network of caves and crevices. Some of these crevices have been shown to contain significant amounts of water, including underground lakes teeming with aquatic organisms like fish and bioluminescent algae. Underground lakes in the Crystal Realm are stable habitats for Tidal Class dragons like Mist Twisters and Flood Fangs due to their size and abundant food sources.

Silver Realm

Within specific sections of the Crystal realm, there exist homogenous formations of crystals, such as an intricate maze area populated by towering pillars of translucent crystals that possess a mirror-like appearance. These crystals are interlaced with veins of silver, creating a visually striking pattern. The densely packed arrangement of these crystal structures results in the formation of a large and complex maze, featuring numerous narrow pathways and dead ends, which pose significant navigational challenges. Additionally, the silver veins within the crystals exhibit properties akin to organic lightning rods, effectively absorbing electrical currents. Dragons equipped with electrical abilities may experience adverse effects when engaging in combat within this environment due to the interference caused by these silver veins.

Fire Realm[]

The Fire Realm

The Fire Realm is a distinct biome characterized by its expansive landscape dominated by molten lava and diverse rock formations. These formations exhibit a wide range of shapes and sizes, including towering pillars, elongated arches, and uneven bridges. This realm is considered one of the most hazardous regions within the Hidden World due to its extreme temperatures and inhospitable conditions.

To navigate safely through the treacherous terrain of the Fire Realm, humans must don fireproof attire to protect themselves from the intense heat. Despite the harsh environment, the Fire Realm supports a diverse array of fauna. This includes plant-like organisms resembling seaweed, snakes with formidable fangs, enormous snails, and lava-dwelling creatures reminiscent of pufferfish.

Dragons that inhabit this realm, such as Catastrophic Quakens, often construct their nests within large, bowl-shaped rock formations.

Ice Realm[]

Ice Realm

The Ice Realm represents a distinct biome characterized by a consistently cold environment, frequent blizzards, and extensive snow cover. The landscape is dominated by numerous large ice structures dispersed throughout the region. Rocky mountains with snowy summits overlook the Ice Realm, while the highest points are adorned with a shimmering Aurora Borealis.

Despite being situated deep underground, devoid of sunlight, the Ice Realm sustains a notable amount of vegetation. This is made possible by the presence of unique crystals that dragons heat with their flames, generating warmer temperatures conducive to plant growth.

King's Realm[]

King's Realm
King's Realm Mountains

The fourth realm, known as the King's Realm, is an expansive mountainous region characterized by towering peaks and rugged cliffs. These mountains exhibit a geological formation featuring various types of rocks, including sedimentary, igneous, and metamorphic rocks, contributing to the diverse topography of the area. The mountains possess jagged edges, steep slopes, and cliffs adorned with red mushrooms. Additionally, numerous caves provide shelter within this realm, while the entrance is protected by booby traps, likely set up by Hiccup and Astrid approximately 1,300 years ago to prevent human intrusion.

Previously inaccessible to most living creatures, the opening of the rift has exposed the lush and vibrant King's Realm. Abundant clusters of crystals, brimming with ancient energy, make this realm particularly alluring. As a result, dragons have begun migrating to the King's Realm in search of a new home. This realm represents a beacon of hope for the future of all dragons due to its ideal combination of vegetation, water, and rock strata, creating a perfect environment.[2]

Nature Realm[]

The Nature Realm, located in the fifth realm, is characterized by its abundant vegetation, encompassing vast stretches of lush landscapes dominated by towering trees and dense canopies. This biome provides ideal nesting habitats for a variety of dragon species, such as Snifflehides and Vine Tails. However, it is important to note that certain plant species within the Nature Realm possess carnivorous traits. These plants utilize thick vines to ensnare and immobilize unsuspecting dragons, drawing them closer to their mouths for consumption. Interestingly, these plants showcase a remarkable resilience to dragon fire and other forms of attack, making them particularly perilous to non-native dragons who are not familiar with their unique biology.

Giant Realm[]

HOH-54-Hidden World

The sixth realm, referred to as the Giant Realm, features a temperate climate that promotes abundant vegetation growth and giant millipedes or centipedes. Within this realm, the grasses reach extraordinary sizes, resembling trees in both height and girth, creating ample hiding places for humans. The Giant Realm is notable for harboring a population of remarkably large dragons, some of which are among the largest known species discovered in the Hidden World. Furthermore, this realm encompasses a vast sea that serves as the habitat for sizable Tidal Class dragons, including Flood Fangs, Octofins, and Shellfires.

Desert Realm[]

HOG-181-Thunder

The seventh realm is the desert realm, made up of a vast desert littered with glass structures created by Glass Casters. Unlike most deserts, the desert in this realm is filled with black sand.

Dark Realm[]

ROJ-110-Hidden World

The eighth realm is the Dark Realm, a dark swampy area of the Hidden World. The place is covered in thick fog and illuminated by red dragonsite. The smoke produced by the red dragonsite causes anger in creatures that breath it in. In the deepest section of this realm holds the darkest secret of all where it was the prison of the most dangerous predator of all dragonkind: Jörmungandr.

Underworld

Another notable area of the Dark Realm is the Underworld. A dark and dreary section of the Hidden World, the most barren area of the rift with few sources of water aside from isolated watering holes. While the ground is mostly sand, Underworld possesses towering crystal hills and mountains which are home to many dragons, particularly Bubblehorns and Spiderwings. The area above the Underworld also contains large amounts of gaseous vapor, which resembles a clouded sky, and even contains its own weather patterns. These vapors can also be ignited by sources of intense heat, namely a dragon’s fire. Some dragons, such as the Crystal Whip, have used this to their advantage when in battle, utilizing the vapors to create fiery tornadoes against their enemies.

Some areas are humid enough to allow moss to flourish, similar to the Bio Realm. Although there are never enough resources to allow large plants to grow, there are small patches of sweet smelling white flowers that add beauty to the realm at the time luring unsuspecting prey.[3]

Gods Realm[]

GodsRealmTrailerPNG

The ninth and final realm is the Gods Realm. It is a large cavern filled with Green Dragonsite. In the center lies a small Dragonsite Crystal held up by three crystal formations, guarded by Gembreakers and flamed upon by a large Gem Blaster dragon, thus oxygenating all the Hidden World. As such, it is thought of as the lungs of the Hidden World.

DreamWorks Dragons: Legends of The Nine Realms[]

Bio Realm[]

Bio Realm

The Bio realm is cavernous with processed bioluminescent mushrooms, crystals and other plants which can serve as light. The crystals live in symbosis with the resident fauna, slowly absorbing excess energy created by dragons like Night Lights and Skrills. Also present are large amounts of salts, minerals, and nutrients, filtered down by the water below. This has nabled many surface-dwelling trees to extend their roots deep down into the rift.[4]

Appearances[]

How to Train Your Dragon: The Hidden World[]

Stoick the Vast believed that the Hidden World is a location where all dragons come from and planned to seal it off to stop the constant fighting between humans and dragons.

Hiccup confided in Astrid about thinking of finding the Hidden World so that everyone in their tribe could live in peace amongst the dragons, and then told the Berkians that they would attempt to find it and relocate there.

The Light Fury was hatched in the Hidden World but eventually made her way to the surface, where she was captured shortly before the film's events. Upon being freed, she led Toothless back to her home, where the resident dragons then paid honor to their new Alpha. Hiccup and Astrid eventually find the caldera while searching for Toothless, but they are chased out by the resident dragons, prompting Hiccup to realize that humans would never be welcome in the Hidden World. It was a place for dragons only.

Following Grimmel the Grisly's death and the Warlords' defeat, Hiccup and the rest of the tribe decided to send all of their dragons to the Hidden World, where no human would ever find and harm them.

Sailing to the Hidden World

A decade later, Hiccup and Astrid take their two children, Zephyr and Nuffink, to the entrance of the Hidden World, where they encounter Toothless, the Light Fury, the Night Light hatchlings, and Stormfly. The fact that the family travels there by boat suggests that the Hidden World is not far from New Berk.

Dragons: The Nine Realms[]

Some time after reuniting with Toothless, Hiccup and the Dragons Riders explore the Hidden World and even making a book about all the different dragons that inhabit the lands and realms. They leave behind artifacts and even set up base in the King's Realm.

Season 1[]

FF2-288-Tom-Thunder-Hidden World

Tom Kullersen and Thunder discovering the Crystal Realm within the Kullersen Fissure.

Dragons have become mere legends in modern times, until a comet nearly collides with Earth, causing a massive tectonic upheaval that creates an enormous, mysterious fissure.

Scientists come from around the world and build a state-of-the-art research facility, including the parents of Thomas "Tom" Kullersen, Jun Wong, D'Angelo Baker and Alexandra "Alex" Gonzalez (who were taken there by their parents), creating Project I.C.A.R.I.S. (International Crevasse and Research Investigation Station). Tom would eventually venture into the Kullersen Fissure, where he would meet a Night Light dragon he later named Thunder. After the two bond, they discover a passage to the Hidden World, an underground realm where all the dragons have been hiding for years. Throughout the series, Tom forms a secret group of dragon riders called the Dragon Club with Jun, D'Angelo, and Alex, who have all bonded with dragons of their own, to protect humans and the secret of the Hidden World from those who would misuse the dragons.

Season 2[]

The Dragon Club's adventures in the Hidden World continue as they discover new caverns and dragons while keeping the secret. There are numerous large chambers and tunnels filled with bodies of water, sand, magma, stalactites, and stalagmites, as well as crystals and crystal-like structures. A vast cavern dubbed the "Crystal Realm" full of warm yellow and golden crystal structures; a vast high-domed area with a sea-like body of water and small sandy crystal islands; another area with such high ceilings that it almost appears to have its own sky; and an area with a labyrinthine forest of tall clear crystals with veins of silver are among the discrete areas where the Dragon Club travels.

As they continue to explore, the gang learns that Tom is descended from Vikings and has a strange connection to the Hidden World. After defeating Thunder's Skrill nemesis, they discovered that another massive chamber of the Hidden World had opened. They also discover an ancient Viking spearhead emblazoned with the Night Fury Strike Class symbol, which matches the symbol on Tom's Viking helmet, alerting the group to the fact that they were not the only ones who ventured into the depths of the Hidden World.

Season 3[]

After discovering the spearhead, the club explores the newest area the Fire Realm with blazing temperatures, boiling lava and discover once again new dragons. However, while exploring for new clues the group finds it even harder to keep the dragons secret. Such as when it came to the club's newest members Jun's brother Eugene who snuck his way into the Dragon's Lair and the others hesitantly allow him to their ranks but while looking for a dragon the group found that the Crystal Realm was under attack by aggressive dragons from the new realm but thanks to Eugene and his new dragon Webmaster they won the battle but the war was far from over.

The group shockingly discovers that the Flamethrower dragons they've been fighting against were only scouts for an even bigger dragon: the dangerous Sky Torcher. Needing help to fight against them and save the Crystal Realm, Tom decided to face his fears along with Jun they ventured to bottom of the Fissure to look for the Fault Ripper dragon finding the beast alive he asked it's for help but meeting again Tom had discovered that the dragon is just like him scarred and afraid from their last encounter. Truly understanding the dragon he repented his actions from before and began to bond with Fault Ripper's help the club drove the Sky Torcher and it's minions back to the Fire Realm and seal off the passage. As a reward, from the Fault Ripper his roar locked another cavern that held a mysterious canister that too had donned the Night Fury symbol bringing the team one step closer to figuring out Tom's past.

Season 4[]

After defeating the Sky Torcher, the Dragon Riders work to keep the Flame Throwers out of the Crystal Realm and in the Fire Realm. They also discover Buzzsaw in the Ice Realm, whom attempts to capture Thunder and kill his rider which he is unsuccessful. However it doesn't stop him from luring dragons like Snowtails and Terrible Terrors into makeshift cages, trapping them and revealing he trained a Timberjack. Tom foils Buzzsaw's plans and the riders rescue the other dragons from the traps which makes Buzzsaw another threat the rider have to defend the Hidden World against. During their trek, Tom had discovered that he already had the key to the canister his viking helmet by using its horn. Tom opened it to discover a book with the same symbol.

As Tom and Thunder search for Buzzsaw near the end of the season, they discover Shadow who turns out to be Thunder's little brother. Shadow leads the riders to the Bio Realm of the Hidden World where they discover booby traps most likely set by Astrid and Hiccup 1,300 years ago. The trail leads them to discover the King's Realm - the new home of Thunder's family. However, they must defend them when predatory Snow Wraiths invade and tries to hunt Thunder's family. Working with the Night Light Elder, Tom and Thunder defeat the Snow Wraiths and force them back into the Ice Realm. Afterwards the Night Light Elder allows Thunder to stay with Tom.

On their way back to the Dragons' Lair, Tom and Thunder fly ahead of everyone and get there first, only to discover Tom's mother, Olivia, had discovered the lair and now knows about the secret Tom and his friends have been keeping.

Season 5[]

When Olivia discovered the secret, she had a hard time accepting it but slowly began to understand why Tom had lied and the bond her son and his friends had with their dragons regardless their adventures went on. They continued on their efforts after the Flamethrowers were saved from Buzzsaw and reunited them with their alpha Sky Torcher. In the process, the Dragon Club discovered a new realm: the Nature Realm. However as they explore deeper into the Hidden World below, Olivia had a hard time keeping the secret up above, making Tom aware that the secret they hide won't be hidden much longer with people getting closer to the dragons. Rakke Town was put into a deep freeze with normal ways of keeping the town alive out of commission. The Dragon Club are forced to call upon their dragons and try to do so undetected, but because of Sledkin, the secret gets out in the form a daring rescue mission where the Dragon Club saves Olivia and Chief Baker and introduces the town their dragons and urges them to keep them secret.

Season 6[]

Just as there were those who respected the dragons there were those who didn't as Buzzsaw continued causing below for the dragons trouble also came from above from Sledkins who was desperate for recognition and to make her mark she saw that dragons as her experimental guinea pigs even more when Olivia reported her findings about the Dragonsite. The club discovered why the dragons depend on it because it oxygenates the whole entire hidden world. Meanwhile as Buzzsaw's corporations were causing trouble below the gang discovered another realm: Giant Realm home of the Floodfangs, Ocofins, Shellfires and Deathgrippers. One of the mad loggers escapades nearly threatened Thunder's life causing Tom to surrender his family ancestor's Book of Dragons and finding out they have been getting worse the club made the decision to tell the adults but to their horror they found Rakke Town a in blaze and Buzzsaw beat them to it.

Season 7[]

Now that the people of Rakke Town are aware of Buzzsaw and him being in possession of the Book of Dragons things become worse as he's able to track down dragons to capture and abuse into forming his dragon army and in pursuit of a legendary death dragon. Though some good things come out of this this such as Philip gaining a Hobgobbler to keep lookout also Tom and Jun beginning their romantic relationship, but things still get worse as Sledkin returns to continue mining her Dragonsite which leads to the Desert Realm and an angry Glass Caster dragon which then leads to the fact of the Realms being based of the Norse Myth Legends of the Nine Realms. Buzzsaw and Sledkin then form an alliance which then becomes much worse as they continue destroying the Hidden World and the dragons however some good news is thanks to Alex the book is rightfully back with the Riders however Buzzsaw's pursuit for his death dragon continues and leads him to the Dark Realm a world of misery and horror.

Trivia[]

  • The Hidden World is a famous myth/legend from the distant seas. It is sometimes called "a world beyond the sunset".[5]
