Visions

The visions are a psychic link to the Powers That Be. They consist of vague images, sounds, and occasionally scents which warn people of dangers.

History
At one point a human girl named Tammy recieved the visions. Unable to handle their power, Tammy eventually died when the visions blew the back of her head out.

At some point in the late 20th century, a half-demon named Allen Francis Doyle was granted the visions. They led him to the vampire-with-soul Angel, putting Angel on the path of his destiny. When Doyle died, he transfered the visions to Cordelia Chase via a kiss. Cordelia, although initally ungrateful for Doyle's "parting gift", eventually came to view them as an asset.

When Cordelia died, she used her last day on Earth to put Angel back on track, and transferred her visions to him as Doyle had to her. Angel recieved only one vision, which led him to bring down the Circle of the Black Thorn.
