I don't know if anyone has had this idea yet, but i think this "Phoenix Lord" title is deeper than him just wanting to sound more powerful or have a better title, and since the mythical phoenix is reborn from its ashes again and again, maybe Ozai is trying for immortality somehow. Could there possibly be a spirit for life and death or maybe a spirit of time? And as there are spirits of ocean and moon, and we have yet to see the spirit of the sun, maybe that spirit takes the form of a pheonix. So i think maybe Ozai does something to a spirit to give him power. This may seem farfetched, i know, but there must be a story behind this title.

i was just browsing through the pics on dongbu feng and i found this.

looks like the south pole got restored quite well by master pakku and the other waterbenders

I did some thinking. My conclusion is that beating the Firelord in a battle seems rather pointless if you try to save the world.

Think about it. No country has ever stopped warfare because there leader died, instead, they just appointed another leader and continued what they were doing, some times this new leader was even more vicious then the one before him.

I want to know what happens after Aang "defeats" the Fire Lord (What is "defeat"? The Fire Lord passed out or the Fire Lord killed?). I suspect both Azula and Ozai will either be imprisoned or killed, but then again, wouldn't some high general take control? I doubt Zuko will take the throne, since he betraid his country not much people will be supporting him. All other relatives, Zuko's mom, Iroh, they all left the FN. The people wouldn't support a traitor, at least I wouldn't.

Furthermore it's doubtfull that the people in the FN are suddenly going to change their minds about the war.

So what will happen? It would logic if some high general would take control and the war would be continued, but I doubt that will happen, since Avatar is still a kids show and needs a happy end. I can't see how though. How is beating the Fire Lord going to stop the war?
