AVATAR:The legend of AGNI

Agni, that was the name of a once great -practically unbeatable- firebender. The Fire Nation glorified this name, some even believed him to be the god of fire. At some point he must have died of old age, though the people no longer seeing him, made them believe in him even more. Obviously he wasn't an actual God? Our Protagonist, the many times over descendant of this once legendary Agni, bearing the same name, was born a bastard, not knowing his father, he adventures the world, reaching for power.
