What is Plurality / Multiplicity / a System?
- More Than One (brief intro to plurality)
- Layman's Guide to Multiplicity (this resource is very old, but most of it holds up. It's not "outdated" as in "bigoted", but has terms that are no longer in wide use like "dark ones", and it mostly is about systems like us: "a system is a group of people and every member is a whole person", as opposed to "a system is one person with dissociated parts". Neither of those is a universal experience. )
- Dispelling Plurality Myths (exactly what it says on the tin)
- Astraea's Web (lots of resources, especially with empowered plurality, including for disordered systems, start with the FAQ)
- Explaining Multiplicity to Children (the "body = house" metaphor)
- Pluralpedia
I'm / we're plural / multiple / more than one and need help!
