A story based of another

I will be writing a story and updating when i can...so here is the prologue...

12^th Moon Rotation, ?? A.D

The Slave’s backs glistened under the harsh sun. The frayed ropes they pulled stretched with its burden, a sandstone block. The Slaves tormentors, or the Slave Masters made sure no one stopped, no one took a break, no one ran away.

“The Pyramid celebrating our empires great discovery is almost finished; it will last to the end of the earth.”
“That is unless someone finds it.”
“Who would look here?”
“You are correct my friend, let us eat to this great accomplishment!”

The two emperors dug in to the lavish meal set before them as they watched the slaves from a cool tent erected under a grove of trees. Exotic fruits and meat caught by the hunters were set upon wooden plates and the meal continued heedless that the discovery they had made will come quite close to destroying the world.
That night under the glow of torches and the pale glow of the moon, halfway hidden by dark, forbidding clouds, the pyramid was finished.

“The tomb is sealed, the powers of this discovery will never be found.”
“Well said my friend, no one except I will know.”
“Excuse me?”

The knife glistened in the dark, drawn from beneath the great emperors robes. It fell, once, twice, and a third time. A scream gurgled from the almost dead emperors lips.

“I’m sorry my friend it had to happen, no one must know.” He gazed down at the body, “remove it, then lets go.” 
Then, underneath the gaze of the still pale glow of the moon, the torches were damped and the warriors fled with their emperor to their ships, back to their ships, back to their desert land, back to their pyramids, away from this strange land. As they looked back they could hear the cries of the land they left behind, leaderless. Then they disappeared into the misty void never to be seen again.
