One of the weakest of dream creatures (and also one of the most commonly encountered), the lemma kertwyn has a vaguely human face and the body of a large fish or (more rarely) bird. It emits small puffs of gray and white vapors from its mouth and nose. Any color is possible for its body, depending on who its creator is. For example, the lemma kertwyn in service to Rune are often vivid, metallic, solar colors with black and gold highlights. All forms of lemma are created by the dream gods directly. The lemma kertwyn serve their creators as messengers and low level skirmishers.
