Vocivian

Vocivian is a xenogender from the element system. It is associated with the element of the void, and represents individuals who either reject or don’t have a gender element. Vocivians can consider the element of void to be the description of their element, or simply say they are void of one. It can be described as being similar to agender or singularian. By its nature, vocivian cannot be combined with other gender elements. The noun form of the word is vocivi (ex: I am vocivi).
