What holds these together
Neurodiversity is usually argued at human scale. These pieces refuse that ceiling. Following Ombre Tarragnat's ethodiversity — the variety of ways of being and behaving across all beings with a nervous system — the nesting runs biodiversity ⊃ ethodiversity ⊃ neurodiversity. Not a rainforest but a chorus: ways of being, all of them whole.
So: the tick's three signals and the mantis shrimp's light, each a complete world rather than a partial version of ours. A council where soil, river, beaver and meadow all get a chair. Organisms that don't merely adapt to a fixed environment but build the environment that then shapes them. The octopus's mind distributed down its arms, the jellyfish's centreless net — no standard nervous system, not across species and not within one.
A declared trilogy
The Council of All Beings, Every Creature's Own Sky and Minor Worlds are a loose trilogy, and Minor Worlds says so itself: how we treat other worlds, how we sense them, and then how we build them. They are kept together and in that order here.
Not the wood-wide-web overreach. Mycorrhizal symbiosis — fungus and root trading minerals for sugar — is settled and ours to use. The forest-wide story is not: Karst, Jones & Hoeksema (Nature Ecology & Evolution, 2023) find the prevalence of common mycorrhizal networks and their benefit to seedlings insufficiently supported, and find no published evidence that elder trees preferentially feed their own offspring. We keep the kinship and name the contested part. It rhymes beautifully with mutual aid, which is exactly why it slipped past us in three pieces before we caught it.
Not speaking for other beings. Giving a creature a chair is not the same as claiming to know what it would say.
The pieces
In the order they were made. The number records when; the collection records what.
