Banshee

Circling all come from the forest when they sense death is approaching, considered an archaic spirit and only dark elves can see or sense their presence. No one else can really see them or hear them.

Banshees are best known for their premonitions. They always appear shortly before the death of someone in their designated family. In a few stories, they have spoken out to tell exactly who would die and how. In most cases, they simply wail—but the Banshee’s wail, in and of itself, is a powerful message. It can be heard for miles and always chills the hearts of the people who hear it. Some stories have described glass windows shattering when hit by the high, plaintive notes of the Banshee’s song.

Origin
Before there were spectral Banshees wandering the hills of Ireland, there were real women who did their job for them! These women, called “keeners,” were hired to grieve either at a funeral or outside of a house where someone was expected to die. Their wailing songs inspired other people to grieve for the dead as well.
