Ishamael
Ishamael was the most powerful of the 13 Forsaken. He was the Chief Commander of the Dark One's forces during the War of Power. Known as the Betrayer of Hope, he ranked high in the Aes Sedai's army before going over to the Dark One. Ishamael also had a heightened psychosis. Some of the other Forsaken believed that he had actually thought himself to be the Dark One. When he was first released from Shayol Ghul, he visited Rand, Mat, and Perrin in his dreams, calling himself Balzammon, the Trolloc name for the Dark One. He was killed by Rand with Callandor at the Heart of the Stone in Tear, but may still be alive in another form, such as the mysterious Moridin.
