(A/N) My friend and I are writing this together, but she doesn't have an account so when I mention her I'll call her SheWhoMustNotBeNamed. She is writing the Percy Jackson characters' perspectives, and I am writing the Gaangs'. Enjoy!

Hazel's POV:

Hazel felt exuberant. They had done it! The Doors of Death were closed. Percy and Annabeth were safe, everyone was, and they had done it! Even Nico was looking full of energy, though he had been ready to drop about half an hour ago. They has all been like that. They were a good distance away from Tartarus now, walking back to meet the Argo II, which was being manned by Coach Hedge the Satyr.

They had camped here in the Underworld (shudder) overnight so that Percy and Annabeth could rest. Though Annabeth's ankle had healed, they has still been in awful shape. But Hazel didn't want to think about that. She wanted to focus on the good things right now. They were going to finish their quest and save the camps, and hopefully have a happy ending.

Of course that's when everything had to go wrong.

Hazel felt something weird down deep in the earth. It felt almost like a lurch, like the earth was churning beneath their feet, only it was a good two hundred fifty feet down. The sensation was slowly creeping up toward them, and it's strength was nearly overwhelming.

"Hazel, what's wrong?" asked Frank, who was walking along next to her. When she looked up at him, his face was full of concern. It distracted her.

The churning was suddenly ten feet beneath them, and her over two hundred feet deep, like mega quicksand or something. "Get back everyone!" Hazel screamed. She should've known it was no good, because the width of this thing was a good fifty-six feet. "Run!" Every hero immediately turned on their heel and sprinted, Frank flying over-head as an eagle to keep up.

There was a loud rumbling that blocked out every other sound except for a loud wailing, as if Gaea had suddenly decided to scream, which she probably did.

Then it reached them. It swallowed them, one by one. Leo, Annabeth, Piper, Jason, Percy, even Frank. Hazel watched as poor Frank was sucked into the swirling dirt, no matter how hard he flied. Nico reached out behind him to grab Hazel's hand, to pull her foreword, but Gaea got there first.

Hazel was sucked into the earth, and her last sight before the dirt buried her was Nico's horrified expression. Then Hazel blacked out.

When she regained consciousness, the first thing she noticed was the cool stone on which she was laying. She sat up and looked around, counting each demigod as she went. Everyone else was still knocked out.

Hazel searched the ground around her with her powers. She was astonished by what she found. Column after column, building after building, a humongous temple-like city made out of earth. Not, correction. Made into the earth. It was part of the earth.

Piper began to stir, so Hazel scooted up to her.

"Piper?" she asked.

"Mmm?" was her answer.

"You okay?"

"Uh... y-yeah," Piper stammered. "Where are we?"

"I have no clue. Some huge temple-structure-thingy," Hazel responded. Piper sat up and looked around. Leo, lying several feet away, opened his eyes and groaned.

"Um... That was- well, I guess weird doesn't cover it, now does it?"

Piper cleared her throat. "Um, I guess not."

Jason woke, then Annabeth, then Percy, until everyone was up and looking around the room. Annabeth spoke up.

"Well, I believe it's safe to assume that our only option here is to explore?" Percy nodded.

"Sounds about right to me."

"Me too," Jason stated.

Everyone nodded their consent on this idea. Helping one another to their feet, they made their way out a nearby door and down a hallway. When they reached a turn, Jason stopped and motioned for them to listen. A second later, they heard,

"Yeah! Just around that corner!: The voice sounded young and female. Before they had a chance to run however, a guy's voice (also young) yelled,

"Alright, come out right now and surrender! We won't fight you if you do that! Come out slowly and we'll talk!" Piper shot them a look saying Leave this one to me. She lead the group of demigods into an opening with six people standing in it, wearing odd clothing.

"Hi, look," Piper said, using her charmspeak. "We just want to talk too, so-" she never finished her sentance. Suddenly, a chunk of earth flew up and clasped her wrist to a wall. Earth spread over the bottom half of her face, silencing her voice.

"She's deceiving us!" cried the same female voice they had just heard.

"Pipes!" yelled Jason, running to her. A young boy, the one who's looks seemed to match the second voice, stepped in front of him, pointing an odd-looking staff at him and said,

"I wouldn't move if I were you."

The group behind him consisted of two guys and three girls. Hazel watched a small blind-looking girl shifting, as if coming out of a fighting stance. Hazel knew that was her opponent, and created a hole at the girl's feet that she fell through, and chaos started as the fighting began.
