Ecology

Sahuagin inhabit deep coastal trenches, sunken city ruins, and warm reef systems too dangerous for merfolk to settle. They live in matriarchal hives organized around a baroness or priest-king who serves the shark-god Sekolah. Their society is ruthlessly hierarchical: the strong eat first, the weak serve, and visible deformity is grounds for ritual exile — except for the rare four-armed birth, which is treated as divine and elevated to priestly rank. They herd sharks like dogs, raid coastal villages for slaves, and keep elaborate underwater cities whose architecture humans rarely see intact.

Behaviour

Sahuagin are predators in mind as well as body. They show no shame about cruelty and take genuine pleasure in hunting wounded prey across miles of dark water. Within the hive they enforce strict obedience through public mutilation and reward bravery with elevated rations and breeding rights. Outside the hive they distrust everything not sahuagin. They observe a single major holy day per year — the Feeding Frenzy — when the priest-king summons sharks to a chosen reef and the entire hive joins a coordinated kill that lasts until the water is no longer red.

Origin

Sahuagin myths cast Sekolah as the first shark, who taught the sahuagin's ancestors to hunt by example and demanded only that they feed his children eternally. Scholars suggest sahuagin descend from an ancient race of intelligent fish whose evolution branched toward humanoid forms tens of thousands of years ago, possibly under aboleth interference. The sahuagin reject this theory with violence and consider any non-Sekolah origin story heretical. The few captured for study tend to attempt suicide before scholars learn anything useful.
