Narayan is the culmination of the lesson Ages Atrus wrote for his sons, to show them the physical embodiment of concepts they needed to understand, were they to write Ages of their own. They had to constantly prune the branches of the trees to keep overgrowth at bay, and bring in new spores to graft as old ones expired. To do this, they would play beautiful tunes on "flutes" or "pipes" to lure these spores toward them, where they would then capture the spores with nets. For the Narayani to survive, they had to capture these spores and graft them into the trees to keep the trees from collapsing into the ocean below. Large milky white spores, what Atrus referred to as "Pearls", would periodically float up from the ocean, through the cloud layer, and into the atmosphere. Extremely large trees called "Lattice Trees" grew from this ocean. Narayan was an Age covered entirely with ocean, no land masses existing.
