The Shadow Dragon is the avatar of Malassa, the Dragon Goddess of Darkness. They take the form of a dragon of onyx, with purple orbs embedded on their wings – these are the eyes of Malassa, capable of seeing any kind of shadows, litterary or metaphorically. The Shadow Lurkers are said to be born from these glowing orbs.
When a Shadow Dragon unfolds its wings in anger, the countless eyes mesmerize its enemies, summoning all kinds of terrifying nightmares in their broken minds. If a more deadly course of action is required, the Shadow Dragons can count on their physical might and their withering breath, that will slowly but surely consume their victim's lifeforce.
The legendary Black Dragons (on the artwork below) are the ultimate evolution of the Shadow Dragons. On their wings, the eyes of Malassa are replaced by intricate patterns of light constantly dissolving, like galaxies being swallowed by the eternal darkness of space.
