Sahuagin
Sahuagin are aquatic humanoids with a strong resemblance to—and affinity for—sharks. They cannot survive long out of water, but in their native environment they are formidable indeed. Those who travel the world’s oceans ignore sahuagin at their peril.
Undersea Marvels. Sahuagin have overcome technological obstacles that some of their undersea neighbors have found insurmountable. They learned of metalsmithing from surface-dwellers centuries ago and have since established their own forges in undersea caves and on islands in waters they control. They have also developed a written language, which they carve into tablets of soft stone. With writing has come cartography, history, and magical traditions. Their religion is focused around a well-developed pantheon of undersea deities, with the shark god most revered of all.
Always Moving. Sahuagin typically follow sea currents, demanding tribute from ships and seaside communities along their route. Those who do not pay can count on being raided, but those who do find that the shark-folk may come to their aid in a crisis.
Consistent as the Tide. Sahuagin believe they own the seas, and disagreeing with them is dangerous. They are loyal, disciplined warriors, and they keep careful records of anyone who gives them trouble. They take umbrage with those who would magically alter the currents they follow, which occasionally brings them into conflict with storm giants and other powerful magical beings. However, those who work with the sahuagin, rather than against them, find them dependable. Sahuagin place considerable value on upholding one’s end of a deal, be it an employment contract, a trade agreement, or a personal promise.
