Sethis-Tir

Sethis-Tir is a yuan-ti anathema and the darklord of a domain where the inhabitants demonstrate dread and veneration for snakes and snake-like entities. Though Sethis-Tir rules his yuan-ti followers from the ruins of an ancient yuan-ti city in a swamp, his minions often take on identities in close human communities to manipulate events and kidnap victims for a variety of nefarious purposes.

Inspiration

Sethis-Tir's domain draws inspiration from H.P. Lovecraft's Innsmouth and David Eddings' Nyissa.
