Tomb of Annihilation
Chwingas are small, shy elemental spirits that live in the rocks, plants, and rivers of Chult.
Chwingas are naturally curious and fascinated by humanoids, who typically wear armor, carry weapons, cook food, and use tools, all things that are alien to chwingas. They possess the ability to take shelter and hide inside their natural surroundings, becoming totally impervious to danger. No chwinga face is alike, as they take star signs, constellations, animal faces, or simply random lines for their face.
