Will o' Wisp
It is not entirely understood what a Will o' Wisp is. Some say they are very weak spirits of the dead as they like to appear in graveyards or other burial sites. Others say they are a type of fairy that uses its various colors to attract the attention of curious travelers and lead them to their fate (which is often deadly). The latter is the most generally accepted and it's suggested that they only hang around graves to look upon their handiwork.
