Always treated as a myth or at least a legend. Not a single species managed to tame them or even comprehend their nature. You can consider yourself insanely lucky if you possess a little part of them, and even more if you've seen one. Some might say their favorite spots are the most dangerous and remote places in Metrecalia. If you find yourself in a situation where you have to fight one, the chances of winning are practically nil.
Legendary and special creatures with an incalculable level of magic. Even rarer than unicorns. There are very few in each ecosystem. Their physical appearance varies from one individual to another, making each one unique. They can be identified by their majestic presence or reptilian form. They may have wings, horns, more than two legs or none at all, long torsos, tails, sharp teeth, among other impressive features. Most have scales and magical powers, such as breathing fire or creating freezing blizzards. They are believed to possess great wisdom, but no one has seen enough of them to corroborate this. They live for centuries and hibernate for decades. It can take years for them to hatch from their eggs, and their body parts are invaluable and used in the most powerful spells. If there is a tier list of the most powerful and impressive monsters, Dragons would take the crown.
