Conjoined Fabrials
Paired gemstone devices — most famously spanreeds — that link two halves of the same spren so motion on one side passes to the other; Navani Kholin is using a new opposed pairing to build the great lifts being constructed on the Urithiru plateau. SA:DS:Ch 1
Known facts
- opposed-pair-platformsCan be paired so the two halves move in opposite directions rather than in tandem — a property Navani's scholars now lattice into the great platforms that lift archers and scouts above a battlefield when a matched lattice is dropped on the far side; the shipboard demonstration on the Wandersail shows the floating hoop ignoring the rolling of the deck because both rings share the same frame of reference.SA:DS:Ch 4
- aluminum-lateral-decouplingHuio accidentally discovers that a sliver of aluminum foil left in a spanreed mechanism breaks the lateral half of a conjoined-ruby pairing while leaving the vertical half intact — meaning a chair anchored to a counterweight on the mast can still slide sideways across the deck under its own power. Rushu recognises immediately that this changes much of what fabrialists had thought possible.SA:DS:Ch 8
