~Beckendorf's POV~

Looking at the wall of the Training Room, it obliviously build for standing up against anything. I have to get Leo to help make something to break the second wall that stood behind the damaged one.

"Have there always been two walls?" Annabeth asked.

We all looked at each other, wanting to know if anyone knew about this, or was it just Percy and Michaela who knew of the second wall.

"The last time this happen-" Phoebe started.

"It was the first time and Michaela-" Kinzie continued.

"She had everyone leave the base, saying-" Zoe continued.

"Saying there was damage in a part of the base that should never be damaged." Bianca finished.

"What does that mean?" Luke asked.

No one answered. I know most of the base, but never knew that there was a second wall behind the first.

And, the second is more re-enforced than the wall showing in the training room...

"The wall was meant to keep something in." I realized. Everyone stared at me.

"Keep what in, Charlie?" Silena asked, looking a little fearful.

I shake my head. "I don't know. But, whatever it is, Percy and Michaela had it locked up somewhere that's not on the map."

Silence surrounded the group, as the situation sank in.

Bianca looked to the wall. "There's something on the other side."

Nico stepped forward. "There's something dark on the other side..." He trailed off, as he walked forward and touched the wall.

Nico is a Son of Hades, and we all are used to his ways, I remember him coming to Camp and the story of what happened to his sister, Bianca.

And, all of us are even used to Percy's dark ways, there are times where he would act like how Nico used to be like. Dark, gloomy, hard to be around, and sometimes, Percy would get into bad fights with Michaela.

But, what happened with Nico's hand when he touched the wall, was not expected.

There was a flash of light and the eight of us Element Wolves, who are under Annabeth (Michaela, when we started out), disappeared.
