Legends and Lore

With a History or Nature check, characters can learn the following:

DC 10 Merfolk are half-humanoid, half-fish. They build villages, towns, and even cities beneath the waves.

DC 15 Merfolk cultures are as varied as those of land-bound folk.

DC 20 Because they have no way of forging it themselves, merfolk value metal. They often trade pearls and other treasures for weapons and tools made of metal.

Description

Aquatic humanoids with the torsos of humans and the tails of fish, merfolk build societies beneath the waves that few land-dwellers ever encounter. Most merfolk keep to the shallows, where light still filters through the water to mark the passage of time. Others, braver or stranger than their coastal cousins, venture into the ocean’s lightless depths. 

Far-Flung Kingdoms. Merfolk kingdoms span the globe and are as varied in culture and appearance as other humanoids. Their skin can be as many colors as a tropical fish. Merfolk who dwell in the shallows tend to be darker-skinned to protect themselves from the sun’s refracted rays, while those who live where the sun cannot reach them are so pale as to be almost truly white, with comfortable layers of body fat to protect them from the cold and pressure. 

Although they sometimes salvage metal from shipwrecks, merfolk rarely use metal in their clothing, jewelry, or tools. Instead, they clothe themselves in seaweed, fish scales, and shells, and use bones, carved coral, and sand-glass for tools. Similarly, they have little use for the writing implements of land-dwellers, relying instead on a capacious oral tradition that extends farther back than most written histories.

Monster Type Description

Humanoids include a number of different intelligent, language-using bipeds of Small or Medium size. Humans and elves are humanoids, and so are orcs and goblins. Humanoids may employ magic but are not fundamentally magical—a characteristic that distinguishes them from bipedal, language-using fey, fiends, and other monsters. Humanoids have no inherent alignment, meaning that no humanoid ancestry is naturally good or evil, lawful or chaotic.
