Royal Blue Dragons were released on January 23, 2012, alongside the Golden Wyverns in celebration of the Chinese New Year and also the beginning of the "Year of the Dragon". Before anyone had any adults, forum users called them "moonlights".

Breeding a Royal Blue Dragon with a Royal Crimson Dragon may produce a Royal Eminence Dragon.

This egg shines in the moonlight.


Aww... It’s a cute baby dragon. It loves watching the reflection of stars in the water.

And look! It has grown wings! It must be close to maturing.


Royal Blue dragons are a nocturnal breed who prefer to live high in the mountains near slow-moving water that reflects the night sky. Although quite capable of defending themselves, they are peaceful by nature and will avoid a fight whenever possible.

Appearance/Basic Anatomy

  • Though males and females have similar markings, the patterns on their face vary and can be used to determine a dragon’s gender.
  • Markings tend to be consistent across dragons, but exceptions do exist.
  • Their eyes are a bright yellow-orange color.
  • Their “crowns” are bone projections covered in skin, rather than typical horns.
  • Adults typically have a saddle-like silver marking on their backs.
  • Silver markings appear as they grow older.
  • No reported sightings of dragons with greater than usual number of horns.
  • Adults with fewer horns than usual seem to have lost them due to injury.

Hatchling Behavior

  • Newly-hatched Royal Blue dragons spend most of their time sleeping.
  • Young Royal Blues form attachments readily and are easy to tame.
  • Hatchlings can often be lured along by bits of shiny material.
  • Hatchlings tend to make high-pitched chirping sounds when excited.
  • Parents keep close watch over the young ones, to keep them from wandering off after any reflective-looking dragons.
  • Hatchlings’ markings may come in at an uneven rate. Though they may temporarily appear to have different markings than usual, the rest will come in with age.
  • Young Royal Blues do not remain with their parents long once they can effectively hunt.
  • Although they may temporarily band together after leaving their parents’ protection, adolescents become more solitary after reaching their full growth.

Adult Behavior

  • They do not breathe fire. However, they do have some form of storing water, which they can exhale in the form of very hot steam.
  • Their steam-breath is most often used in displays, either to impress potential mates or to intimidate and distract adversaries. They also use it to help form and polish their ice caves.
  • They use the stars and moon to navigate, and to help determine when it’s time to move in search of their favorite food sources.
  • Their silvery markings play a large part in their mating rituals. The males tend to choose clear nights around the time of the full moon, the better to posture and show off their reflectiveness.
  • They tend to be particularly fond of dragons with reflective metallic scales. It is not uncommon for them to form close bonds with Nebula dragons as well, because of their shared attraction toward cold weather and observation of the stars.
  • Although during most of the year they will readily take advantage of any naturally-occurring caves for shelter, during the mating season they like to carve out ice caves for themselves. The females begin the initial forming of the caves.
  • They tend to be less vocal as adults than when they are young. Most of the noises they do make could be categorized as coos or chirps. However, when angered they are capable of producing deep roars, all the more startling for their rarity.
  • They are tolerant of other dragons, but spend most of their time alone.


  • When given a choice, they prefer to live close to a source of fresh water.
  • They are occasionally known to dam up streams in order to create reflective pools of static water.
  • They strongly prefer cool temperatures.
  • They are primarily found in mountainous areas.
  • Naturally-occurring caves are likely to attract them to an area.
  • Can sometimes be spotted in warmer areas when searching for food.
  • Mating displays frequently occur on high mountain peaks where snow can be found year-round.


  • Their favorite food is fish.
  • They commonly hunt small mammals.
  • Occasionally hunt cooperatively to bring down large game.
  • Primarily carnivorous.
  • They do not seem to enjoy sweet tastes.
  • Appear to prefer unripe fruit over fully-ripened.
