Revetheralin

Revetheralin are the hauntings of stillborn children.

Details
Revetheralin appear in the dreams of people who have experienced a miscarriage and pose as their dead children, and can kill. They are not like ghouls, and are possibly spirits or the embodiment of malice.

Those plagued by revetheralin are sapped of their energy by the haunting until they die, and tend to sleep more while still alive as a result, though the latter might also simply be going through the experience of a miscarriage, or a combination of the two. Revetheralin make their victims appear heavily grief-stricken and exhausted.

The longer a revetheralin is present, the more dangerous it is.

Witnesses for the Dead can sense revetheralin even by just being in the room with one.

The solution to a revetheralin is for the formerly pregnant person and their family to leave the home where the miscarriage occurred, so that the haunting cannot find them. Having less to do with Ulis in particular is a good idea, and prayers and a pilgrimage to a Sanctuary are all right. The haunted person must also stop despairing, as that is key to the revetheralin's hold: when Cholan Pel-Venna clung to her revetheralin as her only comfort, Thara Celehar told her to let it go, as it was not her child.
