Author's Note: Hi guys! Just so you know, I will try to be releasing either a ton of short chapters or a few long ones. It lets me have a more flexible schedule, and I like it more. The first few chapters will be a bit slow. Remember, this FanFic will have spoilers for all Percy Jackson books, and Undertale. None of the characters from Undertale or Percy Jackson belong to me, they belong to Toby Fox and Rick Riordan. Also, if you have ideas for a better title, please comment them.

Percy awoke to the sounds of cheering. As he got dressed in the empty Poseidon cabin, he was able to make out the two names being cheered: Annabeth and Piper. He stepped outside and saw that they were having a friendly duel.

He began to cheer for Annabeth. He liked Piper, and she was a great friend, but Annabeth was his girlfriend. He had to root for her.

Annabeth disarmed piper, and Piper surrendered. It hadn't really been a fair fight. Apart from the difference in weapon size, the dragonbone sword was much more practical than Katropis, and Annabeth had been training for 3 times as long. If Piper had been allowed to do her charmspeak, she might have won, but it was a strictly melee duel.

Percy walked up to congratulate Annabeth. "Nice job, Annabeth. You destroyed her!" "Nah, it was pretty close. Piper has really gotten better." That was one of the things Percy loved about Annabeth. She was always so modest and supportive, unlike someone he knew.

Think of the devil. Apollo walked into the clearing with his master/best friend, Meg Mccaffrey.

Suddenly, someone pushed him into the ring. He found himself facing Meg.

"Fight! Fight! Fight!"

He drew his sword, Riptide, as Meg unsheathed her two swords. Right as they were about to dive into battle, there was an outburst from near the Hephaestus cabin.

"What do you mean the landmines won't be ready! We have been waiting for a month!" Clarisse, the head of the Ares cabin, was raging at Leo.

"Whoa, calm down! There were some... complications." "How hard is it to build thirty landmines!?" Clarisse was getting incredulous.

As the campers separated them, Leo yelled back: "It was a bit hard to build them with Ares kids throwing smoke grenades into the workshop every 5 minutes!"

Percy sighed. Ever since they had pushed the Triumvirate into hiding, the Ares kids had gotten restless. They had started to take out their anger on the Hephaestus cabin, frustrated that they had not given their landmines highest priority. Still, It was better than having the Triumvirate back.

Even though the Triumvirate had been dealt with, Apollo still had to be Meg's servant for an undetermined amount of time. They had expected him to be bitter, but he was taking it surprisingly well.

Apollo had started his time as a human angry and resentful, but while he was still human he grew accustomed to not having his power. He accepted that he would have to stay as Meg's servant for a while, and getting half of his old powers back was a plus. They were all happy to have Apollo's help defending the camp, especially because he was an amazing archer, very strong, and willing to put himself in danger.

Percy pushed Leo and Clarisse apart. "Clarisse. He's working on it! Give him time. Leo. I know you have nothing better to do. Give her the mines!" Percy was respected by both of them, so they shut up and backed off.

Suddenly, Chiron pushed through the crowds. "Percy, Annabeth, Leo, Piper, Meg, Nico! Come to the big house at once."

"Uh oh." Leo muttered under his breath, "Are we in trouble?" Nobody responded, and they continued walking.

Jason, Ella, Frank, and Hazel were waiting at the entrance to the big house.

"The romans have come to tell us something. I will allow Jason to explain." Chiron stepped back to allow Jason a better view.

"Ella has been saying that she was noticing things that were not in the books of prophecy, and she's panicking. We wanted to know if Rachel had had the same problems, and…" he gestured towards Rachel, who was sitting in her chair muttering with her eyes rolled back in her head.

Suddenly, she sat straight up. She yelled one word at the top of her lungs: "EBOTT!" Then she passed out on her chair.

After they woke her up, she explained that she had no idea what had happened, but she knew that they had to go their. They went on a field trip to the library to look up Ebott.

"I've got something!" Annabeth was quickly shushed by the librarians, but for once she ignored them. "There's a Mount Ebott in Montana. We can take Festus to it."

They returned to camp because Leo needed to make some modifications to Festus to hold extra passengers. They would depart in three days.
