The N'tal are a species of energy beings which came to Earth, requesting bodies for their own dying race; unfortunately for them they are a parasitic species - or as they prefer to call it, symbiotic - and must use host bodies to live longer than two years. Should one grow too old, their regularly golden hue would begin to switch to a blue one, presumably indicating that their energy was starting to dim. At least one individual named Kadmis was able to hold a quasi-humanoid form in order to communicate.
