Sahuagin are a fish-like monstrous humanoid species that lives in oceans, seas, underground lakes, and underwater caves.

Although the correct term to address them as a race is sahuagin, those that fear or despise them usually call them “sea devils” or even more derisively, “fish heads”.

Sahuagin lives in underwater settlements that also has underground passages and tunnels, which connects the houses above the floor. Their society is strictly patriarcal, with a king ruling over princes, who in turn rules over barons.

Each baron rules over a village, while a prince would dominate twenty villages and a king would govern an entire coastline.
