<P> More than a century before the events of the series begin , Fire Lord Sozin , ruler of the Fire Nation , planned a world war to expand his nation 's territory and influence . He was prevented from carrying out his plans by Avatar Roku , who was born in the Fire Nation . After Roku 's death , the Avatar was reincarnated as an Airbender named Aang . Because the Avatar was now a child , Sozin saw his chance and proceeded with his militant plans . At the age of twelve , Aang learned about his avatar status because of the threat of Sozin 's war . Afraid of his new responsibilities and of separation from his mentor Gyatso , he fled his home on his flying bison , Appa . Aang was forced into the ocean by a storm ; he entered the Avatar State and encased himself and Appa in suspended animation in an iceberg near the South Pole for one hundred years . Sozin , knowing the avatar 's reincarnation cycle mandated an Air Nomad was the new Avatar , carried out a genocide against the Air Nomads during the passage of a once - a-century comet that increased the Firebenders ' power , and continued his world conquest . </P>
