Lloigor

Originally, Lloigor was a Great Old One created by August Derleth, said to be the twin of Zhar and child of Shub-Niggurath.

In Colin Wilson's story "The Return of the Lloigor", the name was used to refer to an alien species. These lloigor were naturally "vortices of energy", but could take monstrous, reptilian physical forms. They could also drain energy from humans. Also, they were skilled at altering bodies, and used this to punish human slaves by removing limbs and replacing them with hideous growths and tentacles. These lloigor were led by Ghatanothoa and had no relationship to the Derlethian Great Old One Lloigor.
