Guardians of the Stone

The Guardians of the Stone or just plainly called Birds are protectors of The Nightmare Stone that live on the Nightmare Planet. Apparently they are obedient to whoever is therefore in Stone Nightmares, but they will not hesitate to launch an attack to protect the stone, even against whoever is carrying it.
