Ghosts

Ghosts are a category metaphysical entity that shares many similarities to a spirit. They are the soul or what remains of the soul of an individual who has died. Ghosts can be a controversial subject. They aren't supposed to exist, and many see them as a clear sign that reality is falling apart.
When a person dies their soul leaves the physical realm, and enters a state of limbo between the physical and metaphysical. Any number of things can happen during this time, but at some point the soul will inevitably be sorted out and sent to wherever it's proper destination in the metaphysical realm happens to be. The after life is a complex, bureaucratic nightmare. When the gods were still around, those associated with the domain of death often complained anytime a war began. They lament at, what they referred to as, spiritual paperwork involved in the process.

The Veil

This realm of limbo is referred to as The Veil and is an extension of the domain of death. It is presided over by spirits and minor celestial entities. With souls coming back to the land of the living, It is believed that the veil has been abandoned. With no gods to command them, the entities if the veil cannot do their job, and the souls have nowhere else to go. On the other hand goes to have appeared even when the gods were around. The soul can enter the veil and refuse to be sorted into an appropriate afterlife. Doing so since them back to the land of the living almost permanently. Regardless of the reasoning, the increasing number of ghosts that appear in the world have caused great concern among metaphysical scholars, and furthers the belief that the gods have abandoned reality to its fate.

Anchors

They can attach themselves to an anchor that buys them to physical reality in their current state. This anchor is usually something that they owned in life or something that was precious to them during their life.

This tactic can be just as easily done by a geist or a specter. This makes them even more dangerous as attempting to exercise them will simply send them back to their anchor where they reform and begin their reign of terror once more. In order to successfully eliminate a ghost that has an anchor, one must destroy the anchor first.
