Some life on Nielea is beyond physical bodies, and some seem to have never existed in a non-energy based form. These life forms are known as spirits- though they are not to be confused with the souls of physical life due to the interchangeable use of the word 'spirit' for both. Because they are so mysterious and diverse, many on Nielea have created Spiritariums in their attempts to learn more about this form of life. This category serves to list these life forms.
