It was a calm afternoon in the Black Spike Mountains as the waterfall crashes hard, the air smelled fresh like the Great Jungle, the soil was pure as creatures live in peace and harmony. Deep in the Mountains something rather unusual was discovered inside the mountains by two Po-Matoran brother Archeologists along with a Ga-Matoran translator and a water tribe Agori as secrets shall be revealed.

"Hey Tan, the Bohrok found something!" Tau calling out to Tan, his twin brother

"Hey Tau, what is it?" Tan asking

"Well the Bohrok found this giant door and it's locked too."

"It looks pretty old and a door this size. It must be some kind of Fortress buried in the mountain."

"Let's see if we can get the door opened."

Tau firmly rubs the wall as he is wiping the dust off then pushed a panel unexpectedly that opened the doors slightly as they walked in. Tan spots Ancient writings in order on the walls down the hall but can't make of it and it was beyond dark as they turn on their flashlights.

"Wow, I've never seen language like this before. I wonder, is it Agori or something else?" As Tan wonders and analyzes the symbols

"Must be some kind of encryption. I'm going to go get Gala and Muai."

Tau went to retrieve Gala and Muai outside. Gala; a water tribe Agori the big sister and Muai; a Ga-Matoran the little sister as they examine the symbols on the wall.

"Gala, I've have something on my mind for a long time. Something I hoped someone that would care for me." Muai tells Gala

"And who would that would be little sister?" Gala asks

"Tau."

"Tau?!"

"Tau."

"What makes him so interesting?" Gala asks Muai curiously

"I don't know. He's interesting to me. His work, hobbies and his mask."

"I think your cross wired, sister."

Tau arrived to them

"Gala. Muai. You're not going to believe what we've discovered!"

(Sarcastically) "Let me guess. You found more Rahi to put in your stasis tubes?" Gala asks

"Oh no, something far better than Rahi. Come on, I'll show you."

Tau grabs Muai hand and drags her into the Fortress as she gazes at him. Gala looked very disgusted and followed into Fortress. They returned to Tan and he finished his examination on the symbols on wall.

"Hey your back. Muai. Gala. I want to know if one of you can translate this."

"Well what do you know about it so far?" Muai asks

"Well my results from examining tells me that it's a mixed combination language of Matoran and Agori. Early language before the Matoran's and these are experiment notes too. With all of this old technology this has to be some kind of laboratory and must be at least a thousand years old maybe even much older."

Muai notices something else on the wall "Hey look. There's something else on the wall."

They all followed and seen the unseen. They see blueprints of the Makuta. Teridax. They were very shocked seeing multiple body parts scattered. Gala also notices something on the wall as it shows "WARNING" written on the top.

"Hey look. I think it's a message."

"Well what does it say?" Tau asks

"It's made from both languages. Gala and Muai will have to read it together."

"It says…"

(Both) "For whoever enters this Fortress shall fall into the shadow of the abyss for eternity. If we disturb the lord of shadows. Beware of this warning. Or suffer the consequences."

"What does that mean?" Gala asks and wonders

"It's a warning."

(Breathing) "Tau, stop breathing on me."

"It wasn't me. It's probably the wind."

(Echoing) "The Shadows... shall rise again."

"Who said that?" Muai asked in fright

"It came from over there." They ran over to large metallic body in a throne

(Creepy, demon Voice) (Echoing) (Weakly) "It… is I." Red evil eyes glows as he speaks as it starred down at them. As they were given a chills in their spines.

"Who… who are you?" Tan asks in fright

"And what do you want from us?" Gala asks standing tall

"Nothing... but to give a message."

"Message?" Tau wonders

(Slowly) "Yes."

"What message do want us to bring?" Muai asks

"Your Master will rise again and I… will wreak havoc on this… (Deep breathe) petty world."

"This must be the warning it was talking about."

"I don't want to be in here anymore. Let's get out of here." Said Muai in fright

"Yeah, let's get out of here!" Tau agrees

The four ran for their lives as they over hear the shadow's voice in their heads.

"You may run but you will not survive."

They made it back outside as they retrieve the Bohrok and jumped into the Gala's heavy truck and steamed off as quickly as they can.

"But only time… will tell…"
