The Nyx Heirs also called the Shadow Princes and Princesses were the first creatures to arrive on the land on Nyx, being that the land was inhabited, they decided that they would turn the land into their power source. The Nyx Heirs were all powerful Shadow Creatures, many of them demons while others just held immense dark powers. These Heir's power source came from negative energy, and so they decided the would turn the land into a place of Shadows where their power would grow stronger with every day.
For this to happen, they needed negative emotions to feed off of and then, once of them decided that the only way for that to happen was to bring creatures into the world. The Heir traveled the lands, finding demons, trolls, goblins, all types of evil creatures to feed their power, and so it began, the rule of The Nyx Heirs.
The Nyx Heirs, who lost their powers in sunlight and became mortal beings, decided it was too dangerous to live on land. The created a secret Kingdom under ground, this Kingdom was separated in Twelves different sectors, all which were ruled by each heir.
