As an adult, Allanon is described as seven feet tall and as having a formidable appearance consisting of shaggy eyebrows, a "long flat nose", and penetrating eyes. The impression of him as forbidding is often exacerbated by the long, hooded black robe he commonly wears. He is the adopted son of Bremen of the Druid Order,[4] and carries on his father's legacy as last of the Druids, preserving the knowledge of ancient times, despite the obvious dangers that threaten him. In The Wishsong of Shannara, Allanon's beard has become grey, hinting at his age.
