Nugrath the Sunfather
From The Thalassan Sphere
Summary
King of the Sumpfgotten, Nugrath's priests led the tribes before the founding on yn-av-Agova. Ogor Sun-Blessed raised an army of 10,000 First Men in 39 FYA and marched on the City of Silk and Paper. They were intercepted on the way to the city by a single wizard who called down lightning, wind, and fire on them, killing many and scattering the rest.
The Sons of Nugrath are a cult in Bitu-en-Sul that still follow the Sunfather.
