How to Train Your Dragon

There are no large continents there, only islands and archipelagos.
a time when ballistas and catapults were still in fashion
and there is no electricity, but there is some form of witchcraft

Slayers are a class of dragons distinguished by enhanced intelligence, lightning-fast flight speed, unique appearance, and attack power, and are masters of stealth. Slayers typically have medium-sized bodies and very large wings. Representatives of this class are among the most powerful dragons.

Almost all dragons of this class have unusual flames. For example, the Night and Light Furies produce small exploding clots of plasma, as well as fire of dark blue, purple, or green, while the Skrill produces redirected lightning bolts from clouds of blue. In Dragons: The Nine Realms, Night Light Thunder had purple-hued lightning.

Trackers are a class of dragons whose members have an excellent sense of smell, allowing them to easily locate objects, dragons, and people by scent.

Typically quite robust and small in size, such as the Thunderhorn and the Vile Nadder. Remarkably, most species of this class are new dragons, previously unknown on Berk. Only the Vile Nadders were transferred from the Talon class to the Tracker class, likely because their tracking skills are more valuable than their spines, horns, and claws. Previously, there was a class called the Horror.

Aquatic dragons are one of the most numerous classes in terms of species. All dragons in this class live in or near water bodies and cannot survive for long periods without water.

Most dragons in this class have specialized adaptations for life in aquatic environments: a streamlined body shape, fins, and, in some cases, gills (or other devices that allow them to breathe dissolved oxygen). Some have almost completely lost their connection to land, having evolved flippers instead of legs. Several species have also lost the ability to fly. An interesting feature: the only dragon in this class that breathes fire is the Purple Death; the others use boiling water, poison, electricity, ice, and blasts like the Firebronze as weapons.

Threateners are a vanished class of dragon, these stealthy dragons that sneak up on you when you least expect them.

Once humans got to know dragons better and befriended them, they stopped fearing them. Therefore, there was no longer any need for a class with such a frightening name. Dragons of this class were relegated to the Mysterious category.

Stokers are a class of dragons whose members possess high firepower. It encompasses a wide variety of species, from tiny Firebeasts to the gigantic Red Death. These dragons are extremely dangerous and fiery. For example, the Dread Beast has a habit of igniting itself (like a Moldwing, for example), and the Typhoomerang creates enormous firestorms around its prey, gradually decreasing in diameter, leaving its prey with no chance of escape. The Firebeast is also known to ignite everything it touches and start forest fires, obeying its Firebeast Queen like bees obey their queen. When their health declines, some dragons of this class lose the ability to ignite. Dragons of this class are the kings of fire.

Rock eaters are a class whose members prefer rocky habitats or entire networks of tunnels dug into the ground themselves. They are extremely strong dragons, with mostly tough skin. These dragons typically have very small wings relative to their bodies, but their ability to fly is far from lost. Most species remain poorly understood. Some dragons in this class can digest rocks in their stomachs, withstand fairly high temperatures, and are immune to dragon root.

Talonmen are a class of dragon distinguished by the presence of sharp claws, wings, spines, or horns. Most of these dragons can launch extremely sharp and poisonous projectiles from their body parts, which can quickly regenerate. These are some spiky guys!

Enigmatics are a special class of dragons. They are composed based on the enigmatic nature of certain species. Very little is known about these tricksters, hence their name.
