Hi! This is my first fan-fiction, so brace yourself. I read the 150 things I'm not allowed to do at Camp Half-Blood and 150 things I'm not allowed to do at Mount Olympus stories by KanayaWest/Taylur. I loved the stories, and since she declared she would not be writing for Percy Jackson anymore, I asked permission to do these, and she said yes. So, without further ado, 150 things I'm not allowed to do in the Underworld.

Nico stood on a hill overlooking the fields of asphodel. The Underworld was so freaking boring. He wished he could stay at Camp Half-Blood, but nope. No Hades cabin. Last summer, he had gone into the labyrinth with the ghost of king Minas. This year there was a war. The serious crap going on, the Underworld was gloomier and quieter than ever.

Camp was always fun. The other half-bloods were cheerful even in the face of war. He remembered Annabeth, and Clarisse, and the Stolls…

"The Stolls! That's it!" Nico was inspired. He remembered the Stolls had created a list of 150 things not to do at Camp Half-Blood and done all of them. He knew exactly what to do…

"All right guys, here's the plan…" Nico sat holding a large scroll of paper with the title 150 things I'm not allowed to do in the Underworld. There were a couple of ghosts too, since he had assembled a couple of old friends. Bianca herself sat before him, with a ghostly grin.

"Just don't go too far. Father holds a grudge and can get really mad…" Bianca advised. She was such a goody-goody. Their father, Hades, had a short fuse, and when it ran out, it was an atomic explosion.

"Fine, you won't have to do extreme things. But you'll help, right?" Nico looked at his sister with hope on his face.

"Yeah, I promise I'll help." Bianca smiled. She looked to the other ghosts. Amongst them was the ghost of Castor, son of Dionysus, who had died in the battle of the Labyrinth. Lee Fletcher, son of Apollo, had also died in the battle of the Labyrinth.

"I'm in." Lee agreed, smiling a dazzling smile.

"I'm dead already; I got nothing else to lose." Castor agreed.

Nico smiled.

Let the fun begin.

Okay, I hope that was an acceptable introduction. Those are the only two camper ghosts I could think of, but if you know of any others, please tell me. I do accept any suggestions, and no idea's a bad idea. Soon I will post 150 things I'm not allowed to do at Camp-Jupiter.
