the last airbender series

This is a world shrouded in darkness. The spreading Black Fog corrodes every living creature. The only protection for humanity lies in fire. But as the dark Epoch approached, the fires slowly extinguished. Countless strong Kingdoms became dens for Dark Monsters, humans lost contact with each other, and survivors trembled in the faint solitary light. Until Rod came to this world. "Damn, what's this cow and horse stuff, is it edible?" "This Soul, it's delicious." "As long as the will of fire remains unextinguished, I believe, one day, humanity will once again illuminate this world and burn all spectral vermin to ashes." "Even if I'm mired in darkness, bearing the Dream Realm, I can still support this world!" "We've won!" —— The world is about to fall, the Abyss looms at our side. And I will raise this Unique flame to light up the world. Yes, I am the last King of Darkness. But... Hello? Anyone, save me.
