Welcome to the world of Avatar.
A new Firebending Avatar has yet to be Announced to the world and people are beginning to worry, to plot. Some people believe that the avatar was killed as a young child thus continuing the cycle meaning an Airbending Avatar would be next in the circle. Some groups believe he is being held captive somewhere, others that he is just plane hiding in times of peace.
Recently a new continent has risen from the ocean North East of Bah Sing Se. The Fire Nation has been encouraging people of all nations to share the land and exploration of it, while having no actual claim to it at all.
