On certain nights, they are said come forth from their burial sites to march out to past battles or to other sacred places. Anyone living near their path may hear chanting and marching, and must go inside to avoid notice. They might appear during the day if coming to escort a dying relative to the spirit world. Anyone looking upon or seen by the marchers will die unless a relative is within the marcher's ranks- some people maintain that if you lie face down on the ground they will not see you.Other say that this only works if you are naked. Still others say that you should be naked, lie face up and feign sleep. Placing leaves of the ti (Cordyline sp.) around one's home is said to keep away all evil spirits, and will cause the huaka'i pō to avoid the area.

The first thing you will hear is drums in the distant, then you will smell a foul and musky odor, and you will hear a conch shell being blown, for fair warning to get out of the way, and you will see torches getting brighter and brighter as they get closer.Your best chance is to have an ancestor that recognizes you, they will call out,"Na'u!" which means mine. But if you are in the night marchers bloodline no one in the procession can harm you.No matter what you build in their path the go straight through it.The night marchers are the vangaurd for a sacred chief or chiefess who unusually have a high station in life.Under the kapu system, required commoners to never cast their eyes upon them, doing so will invite swift death.Even the greatest conqueror and king, Kamehameha was required to strip naked and crawl to his wife keopuolani.She was sacred.The nightmarchers do not also serve the ali'i they serve the gods-Akua and Aumakua.So they are more forgiving ad less offended at breaches of protocol.There harbingers are enormous gusts of wind that can tear down branches from the largest trees, sudden storms, or fierce downpours whose drops feels like knives.
