Torivor

Torivors, also known as Lurkers, are an enigmatic extradimensional species summoned to a planet known as Lyrian, where they were enslaved.

Biology
Little is known of true Torivor biology. They are not conventional lifeforms, as they exist in a realm described like a dream, with no concept of time or death, possibly being psychic manifestations or existing in some sort of abstract form not based on matter. When summoned to Lyrian, they took the form of solid humanoids with a generally Human-like shape, but appearing geometrically simple, with no discernable facial features, bodily features, or distinct digits on their feet, although their hands do have digits. Notably, their "skin" is pitch black, with no reflections or shadows from light. Internally, they have a glowing white blood-like substance. When killed, they dissipate, and the only known weapons that can harm Torivors are a unique type of sword made of a material known as Torivorian steel. Torivors are mute, but capable of telepathic speech, and can invade dreams of others, creating nightmares and communicating with victims by disguising as a friend or loved one within the dream. Additionally, Torivors have superhuman speed and strength, infinite stamina, an aura that scares off nearby animals, and the ability to walk on water. They were capable of being controlled by a magical artifact known as the Myrkstone.
