Nyss is a yuan-ti priest stationed in the oracle chamber of the Fane of the Night Serpent, where she and her two fellow priests—Arakiti and Kultha—use a stone basin filled with viscous black and purple liquid to commune with Dendar the Night Serpent. All three priests are loyal to Fenthaza rather than Ras Nsi.
Appearance
Nyss has the form of a type 3 yuan-ti malison: the head and upper body of a dark-skinned woman with the lower body of a snake.
Game Mechanics
Nyss uses the yuan-ti malison (type 3) stat block with the following modifications:
- Enhanced spellcasting: Can innately cast at will—eldritch blast (2 beams; +5 to hit; 1d10 + 3 force damage per beam), minor illusion, and poison spray
- Equipment: Does not carry a longbow
Role in the Adventure
As one of three priests perpetually stationed at the oracle pool, Nyss serves as both a guardian of this sacred site and a conduit for yuan-ti communication with their dark patron. Her loyalty to Fenthaza positions her as a potential ally or obstacle depending on how the party navigates the political tensions within the Fane between Fenthaza and Ras Nsi.
