I'm Aang—and this is the tale of my journey through the Earth Kingdom. I traveled there with my friends Katara and Sokka to find an Earthbending teacher. I'm not sure why, but we ran into trouble almost everywhere we went. We got chased by Prince Zuko's sister, Azula, and got caught in a sinking library. Did I mention that Appa got kidnapped by Sandbenders? There were definitely some scary moments...but I can't complain about getting stuck in the Cave of Two Lovers with Katara! All in a day's work for the Avatar, right?

The basilisks, cruel alien serpents, attacked our world. They bombed us. Hunted us. Butchered us without pity. But now we will be the hunters. We will assemble a fleet. We will cross the vastness of space. And for the first time, we will strike the enemy on his own soil. It's a time for courage. A time for heroes. We will no longer hide in bunkers. We will no longer die like sheep. Freedom will be won with blood and fire. Freedom will be the legacy of Earth. We are the last humans. And we will win!

Earth burns. After generations in exile, we returned to our long-lost planet. Scarred. Haunted. Survivors. We - the last humans - are finally home. But our enemies still crave our blood. Seven alien species unite. Seven fleets bombard our planet. Seven armies invade our beautiful world. They have one goal: To kill us all. We refuse to lose Earth again. We will resist. We will fight for every hill, every valley, every stone, and blade of grass. We will defend our planet. At any cost. Together, we will raise our voices. We will sing the song of Earth. We will tell the enemy: Earth is ours!

We are the last humans. We are hunted. We are refugees. We must return to Earth. The alien scorpions attack us across the galaxy. They butcher millions. Humans are now an endangered species. But we have not given up. We still have a few starships. We still have some hope. And we have a map home. On Earth, we can be free again. On Earth, we can stand tall. On Earth, we can rebuild what we have lost. Earth is but an echo, calling from beyond the darkness. We will answer her call. We will find our lost world. We will defeat our enemies. We will rise again!

The galaxy burns. The enemy, a race of alien scorpions, storms from star to star. Planets smolder in their wake. Across the galaxy, they hunt humans. Long ago, we humans had a planet of our own. Long ago, we could have resisted the scorpions. But today we are refugees. We are lost in darkness. We haven't seen Earth in 2,000 years. We, the last humans, must band together. We must resist. We must fight the scorpions. And we must find Earth! Only Earth can unite us. Only Earth can kindle our hope. Only on Earth can we defend our species.

I am Azula, daughter of the Fire Lord Ozai, and I plan to one day rule the Fire Nation—and the world. But first I have to deal with my good-for-nothing brother, Prince Zuko. Well, he was good for nothing, until he led me to the Avatar! I headed to the Earth Kingdom, where, with the help of Mai and Ty Lee, we trached down the Avatar and his ragtag band. I engaged in a fierce battle with the Avatar himself! I lost that fight, but he should be forewarned: He has not seen the last of Princess Azula.

I am Prince Zuko. After being betrayed by my wicked sister, Azula, Uncle Iroh and I have sought new lives in the Earth Kingdom. It is humbling to wander as a refugee, but it has also opened my eyes to the pain the Fire Nation has inflicted on the world—as well as on me. On one hand I am proud to be a prince of the Fire Nation, but on the other hand I feel very ashamed. What is my destiny? Is it to turn my back on the Fire Nation and start anew, or is it to restore my honor and earn back my rightful place as the future Fire Lord? I have yet to find out.

'm Katara. I'm traveling through the Earth Kingdom with my brother, Sokka, and Aang, the Avatar. After Aang and I studied Waterbending at the North Pole, we set off to find him an Earthbending teacher. The journey has been kind of rough on all of us. I'm having trouble getting along with Aang's new Earthbending teacher, Toph; Aang's struggling with his Earthbending lessons; and we're being chased not only by Prince Zuko, but his sister, Princess Azula, too! But I know we'll make it through this, as long as we all stick together!

I'm Toph. After my father found out that I'd been competing in Earthbending tournaments, he put me under constant surveillance! So I left home. Now I'm traveling through the Earth Kingdom with Aang—he's the Avatar—and his friends Katara and Sokka, on Aang's sky bison, Appa. I'm teaching Earthbending to Aang, and man, do I have my work cut out for me! Even though we've had our differences, it's kind of nice knowing these guys will always have my back and point me in the right direction when I can't feel which way to go.

I am Sokka of the Southern Water Tribe, and I'm the "plan guy" for Team Avatar! Even though I am not a bender, I'm still an awesome fighter with my trusty boomerang. The Avatar and my sister Katara are depending on me to get them safely through the Earth Kingdom, and it has not been easy. I've had to deal with fierce badger- moles, an evil Fire Nation princess, and an Earth King who refuses to acknowledge that there is a war going on! Still, I'm giving it my best shot. After all, the fate of the world is in our hands.

The basilisks. Giant serpents from deep space. Their true name is unknown. Their homeworld is cloaked in shadow. But one thing is certain: They're killers. And they vow to kill us all.
