A life form that is part of the native Narayan ecosystem. It is a huge airborne spore sac that abides in the vaporous atmosphere. They resemble milky-white pearls with some pink. The spores periodically migrate underwater and replenish themselves with hot carbon gases emitted by the geothermal vents. A reinflated spore typically floats up to the surface. A molecular gas exchange causes it to release oxygen replenishing it in the atmosphere. If left attended, they burst in the hot steam.
Narayani harvest drifting spores and Weave the lattice roots into netlike enclosures around them to support growing lattice and force the roots to grow upward. The result is a Lattice Trees and other stable lattice-based structures that form the foundation for Narayani cities. Their civilization is entirely founded upon the ability to capture puffer spores drifting from the geothermal vents. Spores are lured with pipe playing and captured with nets.
Saavedro showed Atrus how the harvesting is done; after weaving a nice into branches, he took him to a rift, where the sea flows through gaps, anticipating the spores. At dusk they begun rising and once they noticed a small one to fit the niche, Saavedro played with his pipe drawing the spore and Atrus threw a net.
