Haunts

Undead spirits burdened by extreme emotion can become tied to a particular place or object and create a haunt. A haunt is a lingering malevolent spiritual force bound to this world. Each haunt is unique but some types of manifestations are more common than others. Some cannot be harmed at all with physical violence or magic spells and instead can only be undone by the correct ritual, somehow appeasing the spirit, or severing the connection between the haunt and the place or object anchoring them to this world. Knowledge is your most powerful weapon against Haunts.
