wisps

Wisps are small, luminous phenomena or beings described as pale, flickering lights that drift through air or across landscapes. The term covers natural optical effects as well as folkloric and fictional representations, and it is widely used in literature, folklore, and contemporary media to describe glowing, ethereal sources of light.

In folklore, the lights are most commonly known as will-o'-the-wisp. They are said to hover above marshes or bogs and to drift in erratic patterns, sometimes appearing as lanterns or wavering orbs that lure travelers off safe paths. In many traditions they are interpreted as spirits, fairies, or tricksters that complicate or mislead those who pursue them. The will-o'-the-wisp motif has appeared in countless stories and regional legends, varying in detail but sharing a common themes of elusive, misdirecting illumination.

Scientific and natural explanations have been proposed for the phenomena attributed to wisps. The most cited is the combustion of gases such as methane produced by decomposing organic matter under anoxic conditions, which can create flickering lights over wetlands. Other possible contributors include bioluminescent organisms or phosphorescent minerals. In many cases, perceptual effects and environmental conditions contribute to the impression of moving, intelligent lights. While popular explanations emphasize natural causes, folklore treats wisps as supernatural or magical beings.

In modern culture, wisps frequently appear as luminous, ethereal entities in fantasy and media. They are commonly depicted as small, intelligent orbs that guide, assist, or tempt characters. Their portrayal ranges from benevolent helpers to mischievous creatures, reflecting the broad spectrum of traditional and contemporary uses of the concept.
