Night Marchers are ghostly apparitions of a band of beings who move with purpose to the beat of primitive pounding drums. Some say they are armed spirit warriors en route to or from battle, toting archaic weaponry and clothed in decorated helmets and cloaks. Other accounts tell of high-ranking ali'i (ruler) spirits being guided to places of high importance or to welcome new warriors to join in battle. Perhaps these restless souls are looking to reclaim rightful territory, replay a battle gone awry, or avenge their own deaths. Some say the Night Marchers are searching methodically for an entrance into the next world. Night Marchers are said to roam through very specific locations and are often recognized by their raised torches and repeated olis, or chants. Although there have been a few scattered reports of daytime marches, these apparitions appear to be most active at night and are said to march on certain nights designated by the moon. And although the Night Marchers allegedly float a few inches off the ground, some local accounts tell of seeing mysterious footprints in their path after they have passed. - To- Hawaii.com Instinct: To walk a trail
