Nix Darkling

Appearance
Nix are mischievous creatures, who are made of fire. They have black bodies, with a tuft of fiery hair on their head, fiery tails, and glowing eyes.

Habitat
Nix live in fires of all kinds, be it a fireplace, forges, or even lava, and can make a fire hotter by dancing within it. Their tales are made of fire, and they can easily catch things on fire without meaning too. Their bodies are also very hot, and are capable of causing burns when they come into contact with other creatures. Most Nix live underground, in hot places, and never enter the overworld.
