Prologue

It was probably stupid of him to leave without telling anyone. But he just wanted to check something out. It was completely harmless.

"You will a die a very painful death," one of the ghosts said.

"Shut up!" he hissed. He was this close to sending their souls to Tartarus.

"Poor thing, doesn't know what lies ahead," one of the older ghosts said, but not directed to him. He gritted his teeth. He took another step forward and realized his mistake too late. He should've checked before he had taken another step. He should've turned around when he still had the chance. He should've been more careful.

The floor crumbled under him and he fell through, not being able to get a hold on the slippery cliff. He screamed. He hit the ground, knocking himself out cold. If only he had listen to Chiron. He could almost hear him now: I told you this would happen, Nico. Some places should be left unexplored.

He messed up, and now he was stuck, completely unconscious, maybe half dead, in a place where no one would ever find him.
