In the headhunter country of Luzon, there is a tree where spirits live. That tree is a symbol of demon power; it is greasy looking and doesn't have a leaf on it, because the worshipers have rubbed their hands all over it and it looks evil. The boughs are gnarled and crooked; and it looks possessed.
The tribe people says that their spirit gods live in it. They offer their offerings and burn incense at the foot of it.
