The Seer

The Seer is an upper level Demon with the power to see the future. ("Charmed and Dangerous"). She is thousands of years old and has served multiple Sources. During the fourth season, she serves as the primary advisor to the Source after the Oracle is vanquished. Besides her power of foresight, she can also send visions to others, presumably only to other people that are capable of seeing into the future, as she did with Phoebe Halliwell ("Womb Raider"), and a form of teleportation that gives a brief outline of her features before vanishing. She is also immune to the powers of upper level demons ("We're Off To See The Wizard"). She also has some form of fire based power as seen in ("Womb Raider") and ("Centennial Charmed").

The Seer is the one who warned the Source against unleashing the Hollow, prophesizing that if he does so, everything will be destroyed and nothing will be left of the world ("Charmed and Dangerous"), and soon after coaxes Cole into taking the Hollow into himself in order to protect Phoebe. After helping to destroy the Source, the Seer seals the Hollow back in its box with the aid of Phoebe. After Cole realizes that he has taken on the Source's powers, the Seer acts as his advisor up until he is vanquished ("Long Live the Queen").

In the episode "Womb Raider," the Seer steals Phoebe's unborn child and the true Source of All Evil and places it in her body by use of a spell. She is vanquished soon after when she attempts to vanquish the sisters by tapping into all of the baby's power, destroying not only her, but also all other demons in attendance of the coronation. So whoever has the power to see the future may have a connection to the Seer.

The Seer returns in Season 5 in the alternate reality created by Cole using Avatar powers, as the advisor to Cole, who is Belthazor again and directly working under the Source.
