Allanon

Allanon is a fictional character from the epic fantasy Original Shannara Trilogy and the trilogy's prequel, First King of Shannara; all four are by Terry Brooks. Described as Brooks' "most enigmatic character", Allanon is very secretive and appears only when needed. He is never completely honest, telling many white lies or half-truths, and informs others with information only if it includes possible risks, if the information is crucial to the task at hand or if the situation calls for it. Allanon considerably lengthened his lifespan through a form of suspended animation called the "Druid Sleep".

Allanon often called on the aid of the Ohmsford family in the novels, as they are descendants of Jerle Shannara and therefore the only ones who can use the Sword of Shannara. He called upon Shea Ohmsford in The Sword of Shannara, Wil Ohmsford in The Elfstones of Shannara and Brin and Jair Ohmsford in The Wishsong of Shannara. In Wishsong, he was killed by a Jachrya.
