Inexian

Inexbeing / Inexian is an umbrella term for alterhuman experiences in which their identity cannot be described, named, or understood by others.

This does not mean that the identity is unknown; rather, the identity itself is something that can’t be understood or described due to its nature. It is possible that the user understands their identity innately, but it is unable to be described or comprehended by other people.

The term was coined by extranth on Tumblr.
