The Kin ships in the Plurality share a common architecture, with a ‘Spindle’, to which banana habitat modules are attached and attachment points for ‘Kataraa’ which provide the ‘Caravan Stack’ with thrust.
During the ‘thrust phase’, the habitat modules are fixed, parallel to the Spindle. During ‘coast phase the habitats detach and rotate with the spindle to create centrifugal gravity.
I haven’t added any additional info on the ship entries yet (no-spoilers before the book is out!!) but here are the links to the Member Area glossary:
