Shadow Spirit

English Folk Marsh Spirit

The Will-o'-the-Wisp is the most famous marsh-spirit of English folklore. The name derives from 'Will of the wisp' (Will carrying a torch of straw), appearing as small flickering blue lights in marshes on dark nights. Folk tradition holds them to be souls of the dead rejected by both heaven and hell, doomed to wander earth eternally and luring travelers to drowning in marshes. Featured in works by Shakespeare, Milton, and Bram Stoker, they have many regional variants including Jack-o'-Lantern and Friar's Lantern.

Logi — Spirit of the Consuming Flame

Logi is the personification of natural flame in Norse mythology, called 'flame itself.' He belongs to the giant race (Jötnar) of massive flames, and though often confused with the trickster god Loki who shares the name, he is a completely different being — Loki is a hybrid of god and giant, while Logi is the pure embodiment of flame. The most famous tale is the eating contest with Loki recorded in the Prose Edda's Skáldskaparmál — when Útgarða-Loki, the giant king of Útgarðr, gave Loki and Logi each a massive trough of meat to compete, while Loki finished only the meat, Logi consumed not just the meat but also the bones and trough itself, winning the contest — a mythological allegory showing the natural law that 'fire burns everything.' He has a massive humanoid body with transparent blue-white flames flowing across his entire body. Anything he touches burns rapidly.

English Folk Will-o'-the-Wisp

Friar's Lantern is a variant name for the will-o'-the-wisp in English folklore, derived from the 16th-century legend of 'Friar Rush,' a mischievous monk-spirit. Appearing as a flickering light in marshes and dark forests, it lures travelers astray. Mentioned in Shakespeare's A Midsummer Night's Dream (where Puck likens himself to it) and Milton's L'Allegro, it belongs to the same family of marsh spirits as the jack-o'-lantern.
