The Serpent Hegemony was a massive empire that, at its height, spread from its point of origin in Sarvoda, across most of Hauner and Heligastenen, and through the northern half of Waritu. Only the continent of Kotime was able to keep relatively free of governance by the Naga and their serpentine allies.

The time that the Serpent Hegemony existed is typically referred to as the Naga Dominion Era.
