Horrorcosmium

Horrorcosmium is a xenogender that is influenced by and/or related to the genre of cosmic horror. It has no recognizable geometric shape or form, making it indescribable. It is characterized by its difficulty to be fully known, its contents often inducing dread and confusion in those who struggle to understand it. This cosmic void induces this dread, as it often causes individuals to look into their inner selves to attempt understanding.

Horrorcosmium can be used as a questioning gender; however, that is not what it is inherently for. It is often used by neurodivergent individuals, but it's not considered exclusive.
