Will-o'-the-Wisp

Historical Background
In British Isles folklore, Will-o'-the-Wisps were faint, eerie roughly orb-shaped lights seen in swamps, marshes, and bogs at night. They were most commonly red, green, or soft blue in color. They were often thought by superstitious Europeans to be mischievous spirits who lead people to their deaths or get them lost in the swamps. The best representation of a Will-o'-the-Wisp in Final Fantasy XI by appearance would actually be the Memory Receptacles. Other names it is known by Ignis Fatuus, Will-o'-the-Wykes, Spunkie, Corpse Candle, Death Candle, Fetch Candle, Elf Fire, Kitty-Candlestick, Hinky-Punk, Pinket, Gealbhan, Irrbloss, Irrlicht, Liekko, Lygtemand, Flammerole, Feu Follet, Annequin, Friar's Lantern, Hobby Lantern, Jack-o-Lantern, Peg-o-Lantern, Pwca, Ellylldan, and Teine Sith. Will-o'-the-Wisps first appeared in English texts in the early 1600s CE. It is the most common name for this phenomenon.
