Much of Allanon's early life is a mystery, save that after his parents abandoned him, most likely due to his magic, he served as apprentice to the seer and Druid Bremen, eventually succeeding him as the world's last known Druid. Thirty years prior to the events of the Shannara Chronicles, the Third War of the Races took place. Allanon fought in that war alongside the young Elven King Eventine Elessedil and Shea Ohmsford, the last heir of the magical Shannara bloodline. Together they defeated the Warlock Lord and brought peace to the Four Lands.
