Lt. Maning is at his navigational consol when he notices something the sensors pick up.

"Captain Lita, sensors have picked up something"

"What is it?" She askes

"Im not sure, It is twice the size of one of our Starbases, but im detecting little to no power output. Scans indicate it is more than a million years old. I am picking up signs of odd energy signatures as well."

"What kind of energy signatures?"

"I dont know, they appear to be interdimensional in nature. Some traces of other energy patters that i cannot identify and can find no records of previously existing."

"Launch a probe at it and hail Starfleet to send several ships into this sector. They would want to take a look at it."

The probe is launched, and it hits the object. The probe goes dead and the object lights up a little."

"What just happened?" The Captain asks"

"It appears once the probe hit the object, the object absorbed all of the energy from the probe, from what it and sensors picked up, i was picking up several subspace signatures emminating from the upper portion of the artifact. I have no clue as to what it is doing, it may be automatted to do something once enough energy is applied. When the fleet gets here, we should attach a reactor to the artifact to see what it does," Maning says.

"Good, tell the fleet to bring an antimatter reactor. I would like to see what this thing does, but keep sensors trained in case we see any sign of hostile activity coming from that artifact," Captain Lita said.

Editors note-This is the end of chapter 1 and the beginning of my first fanfic, next we will bring in the fleet. Hope you all enjoy-Kevin
