Celtic Creatures

Celtic Creatures—wildborn spirits, shape-shifters, and ancient Otherworld beings whose beauty, fury, and uncanny magic blur the line between myth and menace.

The creatures of Celtic lore walk in two worlds at once: the wild, weather-scarred lands of mortals, and the shifting, dream-bright realm of the Otherworld. Born from a culture shaped by stormy coasts, deep forests, standing stones, and ancient barrow mounds, these beings blur the borders between nature and myth, beauty and terror, blessing and bane. In Celtic tradition, the land itself is alive—its rivers, winds, mountains, and ruins watching, remembering, hungering—and its spirits are as fickle as the seasons.

Within this bestiary are creatures of many faces: noble and treacherous fae; spectral omens and death-heralds; shape-shifters bound by charm or curse; beasts touched by primal magic; giants old as mountains; water-haunters that lure the unwary; and the strange, whimsical, or nightmarish entities that slip between folklore and dream. Some protect travellers. Some delight in riddles or tricks. Some drag the living into the deep or the dark. Others simply are—forces of nature, unbound by mortal morality.

Though many of these beings echo across Celtic lands—Irish, Scottish, Welsh, Manx, Cornish, and Breton—each carries a local soul, shaped by its landscape, its clan, its storytellers. A kelpie in a Highland loch may differ from one haunting a storm-fed Irish river; a banshee may be a family guardian in one tale and a harbinger of dread in another. This diversity is the heart of the lore.

This compendium gathers these beings—ancient, wondrous, and terrible—into a single catalogue. Some are drawn directly from myth. Others arrive through centuries of transformation, reinterpretation, and adaptation into fantasy. All share a thread of Celtic spirit: raw, untamed, poetic, and perilously alive.

Whether you wander for inspiration, build a world, forge encounters, or seek the deeper roots of Spiral Worlds, step carefully. In Celtic lands, every shadow has a story, and every story has teeth.
