Ghosts are the spirits of deceased human beings who for one reason or another have been unable to move on. They usually haunt the place they died or where they were buried, though they may also inhabit places where they lived. A ghost can be either good or bad, but generally their behavior is dictated by who they were in life and how they died.
A well-developed ghost character can help bring your story to life, so it’s important that you avoid cliches and give them some depth. They can be as simple or complex as you want, but they should have a backstory and a motivation that connects to the central theme of your story.
Invisibility – Ghosts can remain invisible to the living, appearing only as wispy or distorted forms. They can also manifest as they were in life if they desire, though this requires their concentration. Telekinesis – Ghosts can manipulate objects and the environment around them using only their minds, though this is limited by the size and strength of the object they are trying to move. Very powerful ghosts can even levitate entire rooms and throw people.
Affinity – Ghosts can have natural affinity to elements such as wind, fire, electricity and dropping temperature; this is a result of their mode of death and their origin. For example, drowning ghosts have a natural affinity for water, which they use to lure their victims into danger and prevent them from escaping.
