Seers

The Seer is a title held by demons who can perceive past, present and future events through premonitions and divination.

Overview
Unlike Oracles, Seers can see into the future without the help of crystal balls. The first Seer also once said that she predicted further into the future and more accurately than the oracle, hinting that seers are more powerful than oracles.

Known Seers

 * The Seer: Known only by her title, this Seer served the Source of All Evil for hundreds of years, but was only loyal to herself. Her manipulations resulted in Cole Turner becoming possessed by the Source and Phoebe Halliwell becoming pregnant with his heir.
 * The Crone: Although not using the title, she is considered a Seer. She was a well-respected adviser to powerful evil demons and a powerful demon herself. She was interested in Wyatt Halliwell because of his tremendous power.
 * Kyra: The second demon known as the Seer. She had information on Avatars and wanted to become mortal, as she resented her demonic life.
 * Althea: The third demon known to be called a Seer. She worked for Evil and fell in love with an Oracle named Dinos, and became pregnant with his child. She delivered the child, a daughter that she named Aisling. Her indiscretions led to The Tribunal murdering her by fire.
