Psychoid

Psychoids are a category of extraterrestrials that communicate psychically, by unknown means. Although they usually communicate amongst their own species and with other psychoids, they have the ability to communicate with non-psychoid species, although somewhat limited. Various theories have been made to explain their strange power, from possible radio-wave signals between each other to even communication via the Fifth Dimension. Most psychoid species are very limited physically, many lacking arms or even legs.
