Nagasheni was a naga sacred-historian writing in the Great Expansion, trained in the formal Naga- prefix tradition that marks high-register scholarship. She is the primary written source for the naga mythic account of the Gaeaic Eon — specifically the pre-human period when the naga tradition claims their ancestors witnessed the Walk of Elves and the early dragon territories. Her account is largely irreconcilable with Oblexan's material survey of the same period, a disagreement both scholars acknowledged in writing and neither resolved.
