Sseth appeared to the yuan-ti in the form of a winged yuan-ti claiming to be the Avatar of Merrshaulk. Speaking with Merrshaulk’s voice, Sseth vowed to pull the yuan-ti out of decline and build a new empire. Many of Merrshaulk’s devout turned to the worship of Sseth. Some yuan-ti have long suspected Sseth as an usurper taking advantage of Merrshaulk’s slumber to make himself a god. They believe Sseth might have even devoured Merrshaulk, and now answers the prayers of Merrshaulk’s followers, as his priests convert or consume Merrshaulk’s more stubborn adherents.
