0:01 - 0:03	Water.
0:04 - 0:05	Earth.
0:06 - 0:07	Fire.
0:08 - 0:09	Air.
0:10 - 0:14	Long ago, the four nations lived together in harmony.
0:14 - 0:18	Then everything changed when the Fire Nation attacked.
0:19 - 0:23	Only the Avatar, master of all four elements, could stop them.
0:23 - 0:25	But when the world needed him most,
0:25 - 0:26	he vanished.
0:26 - 0:30	100 years passed and my brother and I discovered the new Avatar.
0:30 - 0:32	An airbender named Aang.
0:32 - 0:34	And although his airbending skills are great,
0:34 - 0:37	he has a lot to learn before he's ready to save anyone.
0:37 - 0:38	Oof.
0:38 - 0:41	But I believe Aang can save the world.
0:41 - 0:43	[ ... ]
0:50 - 0:51	I'm losing this war.
0:51 - 0:53	I'm letting the whole world down.
0:54 - 0:57	I should have seen this war coming, and prevented it.
0:57 - 1:01	For so long, I thought that if my dad accepted me, I'd be happy.
1:01 - 1:03	I'm back home now. My dad talks to me.
1:03 - 1:05	Everything should be perfect, right?
1:05 - 1:07	I should be happy now, but I'm not.
1:07 - 1:10	Please, uncle, I'm so confused. I need your help.
1:11 - 1:14	Forget it. I'll solve this myself.
1:14 - 1:16	Waste away in here for all I care.
1:24 - 1:28	Aang, it's time you learned my history with Fire Lord Sozin.
1:29 - 1:34	You need to understand how the war began if you want to know how to end it.
1:35 - 1:39	Meet my on my home island on the day of the summer solstice.
1:42 - 1:43	Okay, Roku.
1:57 - 2:00	"You need to know the story of your great-grandfather's demise.
2:01 - 2:03	"It will reveal your own destiny."
2:16 - 2:17	There it is.
2:17 - 2:19	That's Roku's home.
2:21 - 2:24	But, there's nothing here.
2:25 - 2:27	Yes, there is.
2:27 - 2:29	An entire village.
2:29 - 2:31	Hundreds of houses.
2:31 - 2:33	All completely buried in ash.
2:38 - 2:41	It's never too early for a sitting with the court painter, Zuko.
2:41 - 2:44	Make sure he gets your good side.
2:45 - 2:46	Wait.
2:46 - 2:47	I need to ask you something.
2:48 - 2:50	What do you remember about our great-grandfather's history?
2:50 - 2:51	Ah, Zuko.
2:51 - 2:53	It's so strange how your mind works.
2:54 - 2:56	Fire Lord Sozin began the war, of course.
2:56 - 2:59	He spent his early years secretly preparing for it
2:59 - 3:01	But he was as patient as he was clever.
3:02 - 3:05	He famously waited for the comet, later renamed Sozin's comet
3:06 - 3:09	and used its power to launch his full-scale invasion of the world.
3:09 - 3:13	In the end, he died a very old and successful man.
3:13 - 3:14	But how did he die?
3:14 - 3:17	Didn't you pay any attention in school, Zuko?
3:17 - 3:19	He died peacefully, in his sleep.
3:19 - 3:20	He was ancient.
3:50 - 3:52	What does it mean?
3:59 - 4:04	"The Fire Sages keep the secret history in the Dragonbone Catacombs."
5:00 - 5:03	"The Final Testament of Fire Lord Sozin."
5:04 - 5:05	Come, Aang.
5:06 - 5:08	Where are we going?
5:08 - 5:10	To visit my past.
5:10 - 5:12	Our shared past.
5:14 - 5:18	As I feel my own life dimming, I can't help but think
5:18 - 5:22	of a time when everything was so much brighter.
5:24 - 5:25	I remember my friend.
5:41 - 5:42	Looks like I win again, Roku.
5:43 - 5:44	Are you kidding?
5:44 - 5:46	The tree root did all the work.
5:47 - 5:49	Nice one, Sozin.
5:49 - 5:52	You were friends with Fire Lord Sozin?
5:52 - 5:57	Back then he was just Prince Sozin, and he was my best friend.
6:02 - 6:03	Say something to her.
6:04 - 6:08	Uh...
6:11 - 6:13	Love is hard when you're young.
6:14 - 6:15	You don't have to tell me.
6:15 - 6:16	Don't worry.
6:17 - 6:18	It gets better.
6:18 - 6:20	Now come with me.
6:20 - 6:22	We have a party to attend.
6:23 - 6:25	Wait, whose party is it?
6:26 - 6:30	Sozin and I shared many things, including a birthday.
6:42 - 6:43	Did something happen to my father?
6:43 - 6:45	No, Prince Sozin.
6:45 - 6:46	We are not here for you.
6:47 - 6:50	We are here to announce the identity of the next Avatar.
6:52 - 6:57	It is our honor to serve you, Avatar Roku.
7:09 - 7:11	Soon, the day came when my friend Roku
7:11 - 7:15	had to leave the Fire Nation and face his destiny as the Avatar.
7:16 - 7:21	He needed to travel the world so he could master the other elements.
7:22 - 7:25	Hey, why aren't you packed yet, all-powerful Avatar?
7:27 - 7:32	Come on, show me how it's done using all four kinds of bending.
7:35 - 7:38	I started packing, but then the Fire Sages told me
7:38 - 7:40	I won't need any worldly possessions anymore.
7:40 - 7:41	Oh.
7:43 - 7:44	It happened so fast.
7:44 - 7:46	Everything's gonna be different now.
7:50 - 7:51	Here.
7:51 - 7:52	I hope you're at least allowed to have this.
7:53 - 7:55	But this is a royal artifact.
7:56 - 7:58	It's supposed to be worn by the crown prince.
7:58 - 7:59	I want you to have it.
8:22 - 8:24	Do they have bathrooms in the Spirit World?
8:25 - 8:27	As a matter of fact, they do not.
8:30 - 8:33	Hey, we're almost at the Southern Air Temple.
8:33 - 8:36	This was the first stop on my Avatar journey.
8:37 - 8:40	It was the place where I was trained to master airbending,
8:40 - 8:45	and also where I met an old friend of yours, monk Gyatso.
8:46 - 8:47	No way!
8:52 - 8:54	Hey, Gyatso, you want to see a new glider trick?
8:59 - 9:01	Check this out.
9:03 - 9:04	He's air-surfing.
9:04 - 9:06	I can't believe I never thought of that.
9:18 - 9:20	That's amazing.
9:20 - 9:23	I can't believe you were friends with monk Gyatso just like I was.
9:23 - 9:30	Some friendships are so strong, they can even transcend lifetimes.
9:33 - 9:39	After my years mastering airbending, I traveled to the Northern Water Tribe.
9:39 - 9:43	Waterbending was especially challenging for me.
9:47 - 9:49	But in time, I mastered it as well.
10:04 - 10:06	I moved on to the Earth Kingdom.
10:10 - 10:16	My earthbending master, Sud, was uncompromising, stubborn, and blunt.
10:18 - 10:21	And a lifelong friend.
10:35 - 10:40	It was bitter work, but the results were worth it.
10:48 - 10:52	Twelve long years passed before I saw my friend again.
10:53 - 10:58	When Roku returned, he was a fully realized Avatar,
10:58 - 11:00	and I had changed as well.
11:00 - 11:04	Sozin, or should I say, Fire Lord.
11:04 - 11:08	Customarily, my subjects bow before greeting me,
11:09 - 11:11	but you're the exception.
11:13 - 11:17	After all these years, he was still my best friend.
11:18 - 11:22	And a few months later, he was my best man.
11:26 - 11:29	Roku, it's that girl who didn't even know you were alive.
11:29 - 11:30	Ta Min.
11:30 - 11:32	I was persistent.
11:32 - 11:36	When love is real, it finds a way.
11:37 - 11:41	And being the Avatar doesn't hurt your chances with the ladies, either.
11:42 - 11:45	On wedding days, we look to the future with optimism and joy.
11:46 - 11:49	I had my own vision for a brighter future.
11:51 - 11:53	Excuse me.
11:53 - 11:55	May I borrow him for a moment?
11:55 - 11:57	It's not very traditional, but okay.
12:00 - 12:02	What's on your mind?
12:02 - 12:05	I've been thinking hard about the state of the world lately.
12:05 - 12:07	Sozin, it's my wedding.
12:07 - 12:08	Have a cookie.
12:08 - 12:10	Dance with someone. Lighten up.
12:10 - 12:12	I know, I know, but just hear me out.
12:15 - 12:18	Right from the start, I was destined to be Fire Lord,
12:19 - 12:22	and although we didn't always know it, you were destined to be the Avatar.
12:23 - 12:26	It's an amazing stroke of fate we know each other so well, isn't it?
12:27 - 12:30	Together, we could do anything.
12:30 - 12:32	Yeah, we could.
12:33 - 12:37	Our nation is enjoying an unprecedented time of peace and wealth.
12:37 - 12:42	Our people are happy, and we're so fortunate in so many ways.
12:42 - 12:43	Where are you going with this?
12:44 - 12:46	I've been thinking.
12:46 - 12:49	We should share this prosperity with the rest of the world.
12:49 - 12:53	In our hands is the most successful empire in history.
12:53 - 12:55	It's time we expanded it.
12:55 - 12:59	No. The four nations are meant to be just that: four.
12:59 - 13:02	Roku, you haven't even stopped to consider the possibilities.
13:02 - 13:04	There are no possibilities.
13:05 - 13:06	This is the last I want to hear about this.
13:09 - 13:12	That was my first real test as the Avatar.
13:13 - 13:16	Unfortunately, it was many years before I learned that Sozin
13:16 - 13:20	had gone ahead with his plan, despite my warning.
13:35 - 13:37	I've seen the colony, Sozin.
13:37 - 13:40	How dare you occupy Earth Kingdom territory?
13:40 - 13:44	How dare you, a citizen of the Fire Nation,
13:44 - 13:46	address your Fire Lord this way?
13:47 - 13:50	Your loyalty is to our nation first.
13:50 - 13:52	Anything less makes you a traitor.
13:53 - 13:54	Don't do this, Sozin.
13:54 - 13:56	Don't challenge me.
13:56 - 13:58	It will only end badly.
13:59 - 14:01	It's over.
14:34 - 14:36	I'm sparing you, Sozin.
14:36 - 14:40	I'm letting you go in the name of our past friendship.
14:40 - 14:43	But I warn you, even a single step out of line
14:43 - 14:47	will result in your permanent end.
15:00 - 15:02	Sozin and I didn't speak or see each other
15:02 - 15:05	for 25 years after our battle.
15:06 - 15:10	I spent most of my spare time here, at my home.
15:29 - 15:31	Let's go.
16:05 - 16:07	Roku's island was 100 miles away.
16:08 - 16:11	But I could still feel it rumbling,
16:11 - 16:13	and see the black plume of smoke.
16:14 - 16:17	I had never seen anything like this catastrophe.
17:10 - 17:11	This is amazing, Roku.
17:11 - 17:14	You're battling a volcano, and you're winning.
17:14 - 17:18	Unfortunately, my success didn't last, Aang.
17:18 - 17:21	There was no way I could do it all.
17:45 - 17:47	Battling the elements was hard enough,
17:47 - 17:50	I had to do it while I could barely breathe.
17:50 - 17:54	The poisonous, volcanic gasses were overwhelming.
17:59 - 18:02	It's all right, Fang.
18:02 - 18:05	Get out of here, I'm fine.
18:28 - 18:29	Need a hand, old friend?
18:30 - 18:31	Sozin?
18:32 - 18:33	There's not a moment to waste.
19:08 - 19:11	Don't breathe the toxic gas.
19:21 - 19:24	It's... Too much.
19:28 - 19:30	Please...
19:32 - 19:35	Without you, all my plans are suddenly possible.
19:35 - 19:38	I have a vision for the future, Roku.
20:12 - 20:16	Who's... Wait, that's me, isn't it?
20:16 - 20:19	Make sense of our past, Aang.
20:19 - 20:24	And you will bring peace and restore balance in the world.
20:24 - 20:25	Roku?
20:26 - 20:28	Roku...
20:29 - 20:32	With Roku gone, and the great comet returning
20:32 - 20:36	the timing was perfect to change the world.
20:36 - 20:40	I knew the next Avatar would be born an air nomad.
20:40 - 20:43	So I wiped out the air temples.
20:43 - 20:46	But somehow, the new Avatar eluded me.
20:47 - 20:51	I wasted the remainder of my life searching in vain.
20:52 - 20:54	I know he's hiding out there somewhere,
20:54 - 20:57	the Fire Nation's greatest threat.
20:57 - 21:00	The last airbender.
21:03 - 21:07	That can't be it, where's the rest of it?
21:15 - 21:17	You sent this, didn't you?
21:18 - 21:19	I found the secret history.
	Which, by the way, should be renamed "The History Most People Already Know."
21:23 - 21:26	The note said that I needed to know about my great-grandfather's death,
21:26 - 21:28	but he was still alive in the end.
21:28 - 21:30	No. He wasn't.
21:31 - 21:33	What are you talking about?
21:33 - 21:36	You have more than one great-grandfather, Prince Zuko.
21:37 - 21:39	Sozin was your father's grandfather.
21:40 - 21:44	Your mother's grandfather was Avatar Roku.
21:45 - 21:47	Why are you telling me this?
21:47 - 21:52	Because understanding the struggle between your two great-grandfathers
21:52 - 21:56	can help you better understand the battle within yourself.
21:59 - 22:02	Evil and good are always at war inside you, Zuko.
22:02 - 22:05	It is your nature, your legacy.
	But, there is a bright side.
22:09 - 22:13	What happened generations ago can be resolved now.
22:14 - 22:15	By you.
22:15 - 22:21	Because of your legacy, you alone can cleanse the sins of our family,
22:21 - 22:23	and the Fire Nation.
22:23 - 22:26	Born in you, along with all this strife
22:26 - 22:31	is the power to restore balance to the world.
22:36 - 22:39	This is a royal artifact.
22:40 - 22:43	It's supposed to be worn by the crown prince.
22:52 - 22:55	You mean, after all Roku and Sozin went through together,
22:56 - 22:59	even after Roku showed him mercy, Sozin betrayed him like that?
23:00 - 23:02	It's like these people are born bad.
23:02 - 23:04	No, that's wrong.
23:04 - 23:07	I don't think that was the point of what Roku showed me at all.
23:07 - 23:08	Then what was the point?
23:09 - 23:12	Roku was just as much Fire Nation as Sozin was, right?
23:12 - 23:16	If anything, their story proves anyone's capable of great good and great evil.
23:16 - 23:19	Everyone, even the Fire Lord and the Fire Nation,
23:19 - 23:21	have to be treated like they're worth giving a chance.
23:22 - 23:24	And I also think it was about friendships.
23:25 - 23:29	Do you really think friendships can last more than one lifetime?
23:30 - 23:32	I don't see why not.
23:32 - 23:35	Well, scientifically speaking, there's no way to prove that...
23:35 - 23:37	Oh, Sokka, just hold hands.
