What is Alterhumanity?

This collection of webpages aims to be a guidebook to alterhumanity, especially pertaining to identification with or as nonhuman species or fictional characters.

For explanations of common terminology and concepts, see Common Terminology; for a curated collection of resources, see Resources, and for a guide to pondering your alterhumanity, see "Am I Otherkin?".

This project began in August 2025, and is still under construction. Each page takes a considerable amount of time and effort to write accurately, I can only ask for patience.
