Outside, Tenzin, and all of his friends and inter-dimensional friends, gathered outside.

"Ikki, Meelo, Rohan, Pema, Isadora, Farkle, Kaya, Bumi and I will ride on Oogi. Lucas, Opal, Kai, Bolin, Mako, Asami, Toph, Lin, Ivan and Harold will ride on Juicy. You four. You'll be riding on Pepper, and Jinora will take control of her." Tenzin Said

"Awwwww. Do we really have to?" Maya said.

"Yes." Tenzin said.

"Don't worry, Tenzin. I'm going to make sure that these three are in good hands. But where does that leave them?" Moose points at Korra and Lord Zuko.

"Don't worry, we've got it all figured out."

Suddenly, A polar bear dog appears from out of nowhere.

"Naga. Let's go." Korra then rides on Naga.

Then, a red Dragon appears in the sky. Lord Zuko rides the dragon

All of them head for the center of the tunnels.

As soon as they locate the location where Moose thinks the tunnels are, Toph uses her foot to to see if the tunnels are there.

"Oh, there's tunnels alright, but they're miles below ground."

"How many miles?" Maya said

"A good 10, Maybe 15 miles. "Toph says

"WOW! The deepest tunnels we found on our dimension are in South Africa, where they are 2.4 miles underground."

"How bad are temperatures inside these tunnels."

"I've read that Air temperatures are in the 100s inside these tunnels. I know. I've been in these tunnels myself."

"WHAT?! How did you get out"

"I found an exit in some kind of desert"

"WHAT DESERT!?"

"The Si Wong desert. Where else?"

Ah, the Si Wong Desert. This is where I did an unforgivable act to Aang by allowing Appa to be captured by the sandbenders. These are truly old memories."

"You mean we have to search for an exit in the middle of thousands of miles of Desert?!"

"No. I know where the entrance is. We need to fly together."

After a week of searching for the entrance in the Si Wong Desert, they find the entrance. Moose instructs them to go in quietly, and that Javier's forces are nearby. He tells them that in the best case scenario, they'll find the airbenders within a week, and that in the worst case scenario, they'll be captured and killed by Javier. After 3 days of Tunnel searching, they enter the Sanctuary.

"Alright, Let's do this." Moose says, roaring like a lion. He says that they should split into 5 groups.

"Team Tenzin, take the South-Side Tunnels into the Cellar. Team Bumi, Take the North-Side tunnels into the left wing of the cellar. Find any airbenders. Watch out for Howlers..."

"Howlers? What the heck are those?" Bumi panicked.

"Howlers. They are bipedal dog-like creatures that are the stuff of nightmares. They're not part of either of your dimensions. Team Farkle, go past Left field and go down to the Steps of Boone. Again, watch out for Howlers and Airbenders. Team Bolin, go down the middle cellar into the second-deepest part of the tunnel. Yet again, Watch out for howlers and airbenders. The green ones are the more powerful ones."

"Then where does that leave us, Moose?" Maya said.

We take the most dangerous part of the tunnels. We need to not only watch out for regular, green and boss Howlers, but Electric slime as well. Believe me, I've dealt with all 4 of them"

"What was it like." Riley said.

Immediately, we see a flashback of Moose getting electrified by the electric slime, as well as being scarred by all three types of Howlers.

"Yikes" Maya and Riley said in Unison.

"Wait, can Jinora come too?"

Moose laughs.

"She's part of our team. TEAM MOOSE!"

Lightning and thunder begins to flash inside the tunnel. His music follows afterwards for like 20 seconds.

"What?!" I'm the avatar. I can bend all four elements, but I can't do that!" Korra yelled.

"You never heard of ring power enhanced with a little bit of Moose and some airbending magic from our best friend?"

"Hey, Wait a second. I just realized something. You need a little Mako as well. What do you say, brother. We trade you for Jinora?"

"Nope, I'm fine with some Fire Ferret Action. and shouldn't Korra be in charge?"

"Your'e right. Korra, you're the Captain of the Fire Ferrets. Asami will be joining you for the mission. OK, LET'S MOVE..."

"Aren't you forgetting something?" Lord Zuko said

"Oh, Right. Lord Zuko, you'll be guarding the sanctuary. Be aware of your surroundings. Always be on the lookout. Here you go."

"What are..."

"Underground Communication Devices, or UCOMDS It enables us to communicate underground, even if we're miles apart. It's water resistant and waterproof." Moose said. "Let's move out."

After battling several threats, including Howlers, Electric slime, and the occasional rogue assassin, they all meet at what Moose dubbed "Point X"

"Whew. It's hot" Maya said.

"Hot? That's nothing. I went to Death valley one summer. It was 129 degrees, and the low temperature was 96 degrees."

"Death valley? Sounds Scary." Jinora said.

Eventually, they all meet at once. Moose rapidly finds the Airbenders holed up. Jinora frees the others. Riley uses a device that counts how many airbenders there should be, excluding Bumi, Maya Tenzin, his children, Kai, and Opal. She finds that there should be 15,000+ airbenders inside this compound. When Tenzin sees this figure, He is floored. "Oh My God. Aang would've loved his." He said.

"Where's Auggie?" Riley said.

Korra's dad took your brother to your mom in the southern water tribe." Moose said.

"Oh. Ok."

All of the airbenders eventually settle at point X, then make their way up the tunnels. Unfortunately, before making their way towards the exit, Javier stops them.

"Well done, my pawns. You fell right into my trap." Just then, a horde of assassins, howlers, Dai Li agents and renegade firebenders, Earthbenders and Waterbenders all converge, blocking their exit. Moose gives a signal to Maya, who gives a signal to Tenzin, who gives a signal to the rest of them.

"LET'S BURN THIS PLACE DOWN!" Moose Roars. Just then, the airbenders, including himself and the Avatar, start blowing all of the assassins, Howlers, Dai Li agents, and renegade firebenders, earthbenders and waterbenders into the walls. Moose instructs Mako to take down Javier, who is momentarily blinded by his lightning powers. He also instructs Maya, Tenzin, and Riley to take down any remaining enemies that stand in their way. As Maya and Riley go with Tenzin, Meelo, Ikki, and Jinora all take down Javier with a cyclonic blast. Then, the rest of the Airbenders and their inter-dimensional friends hightail it out of here. While they do that, Maya, Riley and Tenzin go to Lord Zuko, who tells them that he saw 10 airships. Tenzin is floored at that revelation. He asked him how could they have 10 airships ready. He said that those are not just any airships, they are inter-dimensional airships. Immediately, Maya recognized that those were not airships, but were large spaceships not from their century. Riley couldn't believe it.

"Those ships are from our dimension, but not from this century. What are those?" Riley said, still shocked

"THey're inter-dimensional ships, alright, but scientists said that these ships won't be built for another 865 years." Maya said.

"So how did they get here?" Lord Zuko said.

Just then, a bunch of AI units come to them and offer help. They tell them that those ships can carry 15,000 people at a time. They also mention that they are impervious to almost anything that inter-dimensional travel can throw at them. The only thing that could stop them are Gamma Rays. When Maya heard the word Gamma Rays, she immediately remembered the comet.

"I get it now. The comet is green because it emits Neon"

"What comet?" Toph said, coming out of the tunnel.

"Sasha's comet. It comes in less than a week." Riley explains.

"Then we better all board the ships."

As all of them came out, Maya, Riley, Tenzin and Lord Zuko all notice that all of the Airbenders are safe, except for a couple of them, who sustained minor wounds from the howlers.

All 21,370 airbenders board the 10 airships, and then thank Moose for the rescue.

"It's been a pleasure to serve you guys. Now let's say we go back to Ba Sing Se and Celebrate." Moose said.

The gang all ride on the 3 flying bison, and head off to Ba Sing Se, where an unexpected guest arrives.

Now, you may be thinking, who's the unexpected guest? Well, it's a guest you're all quite familiar with in the GMW Universe. In fact, She and Auggie were an item in GMW.
