0:02 - 0:04	Water...
0:04 - 0:06	Earth...
0:06 - 0:08	Fire...
0:08 - 0:10	Air.
0:11 - 0:14	Long ago, the four nations lived together in harmony.
0:15 - 0:18	Then everything changed when the Fire Nation attacked.
0:19 - 0:22	Only the Avatar, master of all four elements,
0:22 - 0:23	could stop them.
0:23 - 0:25	But when the world needed him most,
0:25 - 0:26	he vanished.
0:27 - 0:28	100 years passed,
0:28 - 0:31	and my brother and I discovered the new Avatar―
0:31 - 0:32	An airbender named Aang.
0:32 - 0:35	And although his airbending skills are great,
0:35 - 0:38	he has a lot to learn before he's ready to save anyone.
0:38 - 0:39	Oof.
0:39 - 0:42	But I believe Aang can save the world.
0:51 - 0:53	I discovered a hidden library.
0:54 - 0:56	I tore through scroll after scroll.
0:59 - 1:01	You did it!
1:01 - 1:02	You're an earthbender.
1:03 - 1:06	Sozin's Comet will return by the end of the summer.
1:06 - 1:10	And Fire Lord Ozai will use its power to finish the war
1:10 - 1:11	once and for all.
1:12 - 1:14	You must defeat the Fire Lord
1:14 - 1:16	before the comet arrives.
1:26 - 1:27	What's out here?
1:27 - 1:30	A lot, actually. There's hundreds of little―
1:30 - 1:32	Shh! I know you can see underground,
1:32 - 1:34	but don't ruin the surprise.
1:34 - 1:35	Just watch.
1:37 - 1:38	Eh
1:38 - 1:39	Ha ha! Yeah!
1:41 - 1:42	Eh!
1:42 - 1:44	I'm putting an orchestra together.
1:44 - 1:45	Orchestra, huh? Well...
1:45 - 1:47	La-di-da
1:47 - 1:49	Laah Diih
1:49 - 1:50	Daah
1:53 - 1:54	Eh
1:54 - 1:55	Eh!
1:56 - 1:57	Eh!
1:57 - 1:58	Eh
1:59 - 2:00	This is great and all,
2:00 - 2:03	But don't we have more important things to worry about?
2:03 - 2:04	We should be making plans.
2:04 - 2:06	We did make plans.
2:06 - 2:07	We're all picking mini-vacations.
2:08 - 2:10	There's no time for vacations.
2:10 - 2:12	I'm learning the elements as fast as I can.
2:12 - 2:15	I practice hard every day with Toph and Katara.
2:15 - 2:17	I've been training my arrow off.
2:17 - 2:20	Yeah. What's wrong with having a little fun in our downtime?
2:20 - 2:23	Even if you do master all of the elements, then what?
2:23 - 2:25	It's not like we have a map of the Fire Nation.
2:25 - 2:28	Should we just head west until we reach the Fire Lord's house?
2:28 - 2:31	Knock, knock! Hello, Fire Lord! Anybody home?
2:31 - 2:32	I don't think so.
2:33 - 2:35	We need some intelligence if we're gonna win this war.
2:35 - 2:36	Laah
2:36 - 2:39	Hee hee! All right. We'll finish our vacations.
2:39 - 2:41	And then we'll look for Sokka's intelligence.
2:43 - 2:44	Your turn, Katara.
2:44 - 2:46	Where would you like to go on your mini-vacation?
2:46 - 2:49	How about the Misty Palms Oasis?
2:49 - 2:50	That sounds refreshing.
2:50 - 2:53	Oh, yeah, I've been there. It's a pristine natural ice spring.
2:53 - 2:56	And I don't usually use the word "pristine."
2:56 - 2:58	It's one of nature's wonders.
3:00 - 3:03	Must have changed ownership since I was here.
3:03 - 3:05	Heh heh.
3:15 - 3:16	Ptooey!
3:27 - 3:28	One mango, please.
3:42 - 3:44	I don't see anything wrong
3:44 - 3:46	with having one of those fruity beverages
3:46 - 3:48	while we plan our strategy.
3:49 - 3:50	Excuse me.
3:54 - 3:56	No worries. I clean up easy.
3:59 - 4:00	You're a living relic.
4:00 - 4:01	Thanks. I try.
4:02 - 4:05	An Air Nomad right front of me.
4:05 - 4:06	Professor Zei, head of anthropology
4:07 - 4:08	at Ba Sing Se University.
4:08 - 4:10	Tell me...
4:10 - 4:13	Which of the air temples do you hail from?
4:13 - 4:14	The Southern Temple.
4:14 - 4:16	Oh, splendid! Now, tell me,
4:16 - 4:19	what was the primary agricultural product of your people?
4:19 - 4:23	Uh, are fruit pies an agricultural product?
4:23 - 4:27	Oh! Truly fascinating. That's one for the journal.
4:27 - 4:30	So, professor, you're obviously a well-traveled guy.
4:30 - 4:32	Do you have a more current map?
4:32 - 4:33	Ours seems to be a little dated.
4:34 - 4:35	Certainly.
4:38 - 4:40	What? No Fire Nation?
4:40 - 4:42	Doesn't anybody have a good map of that place?
4:43 - 4:45	You've made a lot of trips into the desert.
4:45 - 4:46	All in vain, I'm afraid.
4:47 - 4:50	I've found lost civilizations all over the Earth Kingdom,
4:50 - 4:53	but I haven't managed to find the crown jewel―
4:54 - 4:56	Wan Shi Tong's library.
4:56 - 5:00	You've spent years walking through the desert to find
5:00 - 5:01	some guy's library?
5:02 - 5:05	This library is more valuable than gold, little lady.
5:05 - 5:09	It is said to contain a vast collection of knowledge.
5:09 - 5:10	And knowledge...
5:11 - 5:12	Is priceless.
5:12 - 5:14	Hmm. Sounds like good times.
5:14 - 5:17	Oh, it is. According to legend,
5:17 - 5:20	It was built by the great knowledge spirit
5:20 - 5:24	Wan Shi Tong with the help of his foxy knowledge seekers.
5:24 - 5:28	Oh, so this spirit has attractive assistants, huh?
5:28 - 5:30	I think he means they look like actual foxes, Sokka.
5:30 - 5:32	You're both right.
5:32 - 5:33	Handsome little creatures.
5:33 - 5:36	Wan Shi Tong and his knowledge seekers
5:36 - 5:38	collected books from all over the world
5:38 - 5:41	and put them on display for mankind to read
5:41 - 5:43	so that we might better ourselves.
5:43 - 5:45	If this place has books from all over the world,
5:45 - 5:48	do you think they've got info on the Fire Nation? A map maybe?
5:48 - 5:49	I wouldn't know.
5:50 - 5:52	But if such a thing exists,
5:52 - 5:54	it's in Wan Shi Tong's library.
5:56 - 5:59	Then it's settled. Aang, I do believe it's my turn.
5:59 - 6:02	I'd like to spend my vacation at the library!
6:03 - 6:07	Uh, hey, what about me? When do I get to pick?
6:07 - 6:09	You've got to work here a little longer
6:09 - 6:11	before you're qualified for vacation time.
6:11 - 6:12	Hmph.
6:12 - 6:14	Of course, there's the matter of finding it.
6:14 - 6:16	I've made several trips into the Zi Huang desert
6:16 - 6:18	and almost died each time.
6:18 - 6:21	I'm afraid that desert's impossible to cross.
6:22 - 6:25	Professor, would you like to see our sky bison?
6:25 - 6:29	A sky bison? You actually have one?!
6:31 - 6:34	Sandbenders, shoo! Away from the bison!
6:55 - 6:58	Tell me, sky bison, are you the last of your breed?
7:00 - 7:03	Oh, delightful! I only wish I spoke his tongue.
7:03 - 7:06	Oh, the stories this beast could tell.
7:08 - 7:09	Shush, chatty monkey.
7:10 - 7:12	Wow. It shouldn't be too hard
7:12 - 7:13	to find a place like this out here.
7:18 - 7:20	Ah! Does this place even exist?
7:20 - 7:22	Some say it doesn't.
7:22 - 7:25	Shouldn't you have mentioned that before?
7:25 - 7:26	Grr!
7:32 - 7:33	There it is!
7:37 - 7:40	That's what it will sound like when one of you spots it.
7:45 - 7:48	It shouldn't be this hard to spot a giant ornate building from the air.
7:52 - 7:54	Down there. What's that?
7:59 - 8:02	Forget it. It's obviously not what we're looking for.
8:02 - 8:04	The building in this drawing is enormous.
8:13 - 8:14	What kind of animal is that?
8:18 - 8:20	I think that was one of the knowledge seekers.
8:21 - 8:23	Oh, we must be close to the library.
8:23 - 8:26	No. This is the library. Look!
8:29 - 8:30	It's completely buried.
8:38 - 8:40	The library is buried?!
8:40 - 8:43	My life's ambition is now full of sand.
8:44 - 8:46	Well, time to start excavating.
8:49 - 8:52	Actually, that won't be necessary.
8:52 - 8:54	The inside seems to be completely intact.
8:54 - 8:56	And it's huge.
8:56 - 8:58	That fox thingy went in through a window.
8:58 - 9:00	I say we climb up there and give it a look.
9:00 - 9:03	I say you guys go ahead without me.
9:03 - 9:05	You've got something against libraries?
9:05 - 9:06	I've held books before.
9:06 - 9:08	And I got to tell you,
9:08 - 9:10	they don't exactly do it for me.
9:10 - 9:12	Oh, right. Sorry.
9:13 - 9:15	Let me know if they have something you can listen to.
9:20 - 9:24	Don't worry, buddy. I'm not making you go underground ever again.
9:24 - 9:26	You can stay out here with Toph.
	What's up?
9:43 - 9:45	Oh, it's breathtaking.
9:46 - 9:49	The spirit spared no expense in designing this place.
9:49 - 9:51	Look at those beautiful buttresses.
9:51 - 9:52	Hee hee! Hee hee!
9:52 - 9:54	What's funny?
9:54 - 9:56	Nothing. We just like architecture.
9:56 - 9:58	As do I.
10:01 - 10:02	My word!
10:02 - 10:07	The exquisite mosaic handiwork of this tile-rendered avian symbol―
10:07 - 10:10	Eh, nice owl.
10:26 - 10:28	I know you're back there.
10:31 - 10:32	Hello!
10:32 - 10:34	I'm Professor Zei, head of anthropology
10:35 - 10:36	at Ba Sing Se University.
10:37 - 10:39	You should leave the way you came
10:39 - 10:43	Unless you want to become a stuffed head of anthropology.
10:45 - 10:48	Are you the spirit who brought this library to the physical world?
10:48 - 10:53	Indeed. I am Wan Shi Tong, he who knows 10,000 things.
10:53 - 10:55	And you are obviously humans,
10:55 - 10:58	Which, by the way, are no longer permitted in my study.
10:58 - 11:00	What do you have against humans?
11:00 - 11:03	Hmm. Humans only bother learning things
11:03 - 11:05	to get the edge on other humans,
11:05 - 11:09	Like that firebender who came to this place a few years ago,
11:09 - 11:11	looking to destroy his enemy.
11:12 - 11:15	So who are you trying to destroy?
11:15 - 11:19	What? No, no, no destroying. We're not into that.
11:20 - 11:22	Then why have you come here?
11:22 - 11:26	Um, knowledge for knowledge's sake.
	If you're going to lie to an all-knowing spirit being,
11:30 - 11:33	you should at least put some effort into it.
11:33 - 11:35	I'm not lying! I'm here with the Avatar,
11:35 - 11:38	And he's the bridge between our worlds. He'll vouch for me.
11:39 - 11:40	Ow!
11:40 - 11:43	Uh, yeah. I'll vouch.
11:43 - 11:46	We will not abuse the knowledge in your library, good spirit.
11:46 - 11:48	You have my word.
11:48 - 11:53	Hmm. Very well. I'll let you peruse my vast collection
11:53 - 11:55	on one condition―
11:55 - 11:57	To prove your worth as scholars,
11:57 - 12:01	you have to contribute some worthwhile knowledge.
12:02 - 12:05	Please accept this tome as a donation to your library.
12:06 - 12:08	First edition. Very nice.
12:12 - 12:14	I have an authentic waterbending scroll.
12:15 - 12:18	Oh, these illustrations are quite stylish.
12:20 - 12:22	Uh, oh! I know.
12:23 - 12:24	Ha!
12:25 - 12:27	I suppose that counts.
12:29 - 12:31	Oh, great spirit, check this out.
12:32 - 12:33	Ta-da!
12:34 - 12:36	It's a special knot.
12:36 - 12:37	That counts as knowledge.
12:38 - 12:40	You're not very bright, are you?
12:42 - 12:44	Enjoy the library.
12:51 - 12:53	Bright enough to fool you.
12:56 - 13:00	So, do you like flying?
13:02 - 13:05	Of course, I'm more comfortable on the ground where I can see.
	Well, I don't see the way you do.
13:08 - 13:11	I feel the vibrations in the ground with my feet.
13:11 - 13:14	But this sand is so loose and shifty,
13:14 - 13:16	It makes everything look fuzzy.
13:18 - 13:20	Not that there's anything wrong with fuzzy.
13:31 - 13:33	Hey! Look at these weird lion-turtle things.
13:34 - 13:36	Ah, I've seen weirder.
13:36 - 13:39	Aang, did you know in a past life, you were left-handed?
13:39 - 13:41	I always knew I was special.
13:51 - 13:54	"The darkest day in Fire Nation history."
13:55 - 13:56	It's got a date at the top,
13:56 - 13:58	but it doesn't say anything else.
14:04 - 14:06	Sokka, where are you going?
14:06 - 14:10	I want to know what happened to the Fire Nation on their darkest day.
14:10 - 14:11	This could be promising.
14:13 - 14:16	The information on the Fire Nation should be right up here.
14:19 - 14:20	Firebenders.
14:20 - 14:23	They destroyed everything having to do with the Fire Nation.
14:24 - 14:25	That's so unfair!
14:25 - 14:28	Just when I think I'm one step ahead of the Fire Nation,
14:28 - 14:31	it turns out they beat us here a long time ago.
14:31 - 14:34	I need to know what happened on the darkest day.
14:36 - 14:39	Hello, little weird fox guy.
14:42 - 14:44	It seems it's trying to assist you.
14:44 - 14:48	Um, sure. I guess I'll follow you.
15:15 - 15:19	This room is a true marvel, a mechanical wonder.
15:19 - 15:22	It's a planetarium that shows the heavens moving.
15:25 - 15:28	This is beautiful, but how is it helpful?
15:29 - 15:32	Maybe these dials represent dates and times.
15:32 - 15:35	Sokka, try entering that date from that parchment you took.
15:35 - 15:40	Shh! Katara, not in front of the fox. He's with the owl.
15:59 - 16:01	Wow! I got to hand it to you, Sokka,
16:02 - 16:04	You picked the best mini-vacation for sure.
16:08 - 16:10	Hey, wait. What happened to the sun?
16:11 - 16:13	Great. You must have broken it.
16:14 - 16:15	It's not broken.
16:17 - 16:20	The sun is behind the moon. It's a solar eclipse.
16:21 - 16:24	It's literally the darkest day in Fire Nation history.
16:24 - 16:26	Now I get it. Something awful happened on that day.
16:26 - 16:28	I don't know what, but I do know why.
16:29 - 16:32	Firebenders lose their bending during a solar eclipse.
16:32 - 16:33	Sorry.
16:34 - 16:35	That makes sense.
16:35 - 16:37	I mean, think of what the lunar eclipse at the North Pole
16:37 - 16:39	did to the waterbenders.
16:39 - 16:40	This is huge.
16:43 - 16:45	Fine. You earned it.
16:47 - 16:50	We've got to get this information to the Earth King at Ba Sing Se.
16:50 - 16:52	We'll wait for the next eclipse.
16:52 - 16:55	Then we'll invade the Fire Nation when they're totally helpless.
16:55 - 16:57	The Fire Lord is going down!
16:57 - 17:00	Mortals are so predictable
17:00 - 17:02	and such terrible liars.
17:09 - 17:11	You betrayed my trust.
17:11 - 17:14	From the beginning, you intended to misuse this knowledge
17:14 - 17:15	for evil purposes.
17:16 - 17:19	You don't understand. If anyone's evil, it's the Fire Nation.
17:19 - 17:21	You saw what they did to your library.
17:21 - 17:23	They're destructive and dangerous.
17:23 - 17:25	We need this information.
17:25 - 17:29	You think you're the first person to believe their war was justified?
17:29 - 17:31	Countless others before you have come here,
17:31 - 17:34	seeking weapons or weaknesses or battle strategies.
17:35 - 17:38	We had no choice. Please. We're just desperate to protect
17:38 - 17:39	the people we love.
17:39 - 17:43	And now I am going to protect what I love.
17:47 - 17:48	What are you doing?
17:48 - 17:54	I'm taking my knowledge back. No one will ever abuse it again.
17:54 - 17:57	He's sinking the building. We've got to get out of here!
17:57 - 18:01	I'm afraid I can't allow that. You already know too much.
18:01 - 18:03	Aah! Aah!
18:12 - 18:14	I already told you. I don't want to snuggle.
18:19 - 18:22	Library's sinking. Library's sinking!
18:23 - 18:25	Hyah!
18:51 - 18:52	Aah!
18:53 - 18:55	Great knowledge spirit, I beg you,
18:55 - 18:59	do not destroy your vast collection of priceless tomes.
19:00 - 19:02	Aah!
19:10 - 19:12	We've got to get back to the surface.
19:14 - 19:16	Sokka, let's go.
19:16 - 19:19	But we still don't know when the next eclipse is gonna happen.
19:19 - 19:21	Don't be stupid. We'll find out later.
19:21 - 19:23	No, we won't. If we leave this place,
19:23 - 19:25	we'll never get the information.
19:25 - 19:27	Aang, come with me to the planetarium. I need cover.
19:28 - 19:29	Katara, take Momo and get out of here.
19:30 - 19:31	But―
19:31 - 19:32	Go!
19:32 - 19:33	Hurry, Sokka!
19:48 - 19:50	What is it now?
19:58 - 19:59	Who is there?
20:07 - 20:08	Why are we doing this?
20:08 - 20:11	Because if this calendar can tell us about eclipses in the past,
20:12 - 20:14	then maybe it can project when the next one will be.
20:14 - 20:16	You can't possibly check every single date.
20:16 - 20:18	I don't have to. We just need to check
20:18 - 20:20	every date before Sozin's Comet arrives,
20:20 - 20:24	because after that, well, try not to think about that.
20:44 - 20:45	Come on, eclipse!
20:49 - 20:51	That's it― The solar eclipse.
20:51 - 20:53	It's just a few months away.
20:54 - 20:57	Got it! Now let's get to Ba Sing Se.
21:15 - 21:17	Don't make me put this down.
21:27 - 21:29	No! Stop sinking!
21:34 - 21:35	No!
21:36 - 21:37	I'm sorry, Appa.
21:56 - 22:00	At least I'll have one specimen to add to my collection.
22:00 - 22:01	Aah!
22:11 - 22:13	Your waterbending won't do you much good here.
22:14 - 22:17	I've studied northern water style, southern water style,
22:17 - 22:20	even foggy swamp style.
22:21 - 22:23	Hyah!
