Underground City

The secret of this world was hidden under their nose.

The rumbling came from inside the pyramid as if a ton of stones were rolling inside. Dust and debris began to fall from above when the pyramid finally opened.

The old mechanism was pushing a series of huge stones out from the side of the pyramid, which had no doors or windows. Each stone weighed more than ten tonnes, had mysterious runes at the bottom that glowed in blue and red, and floated in the air in defiance of gravity. Instruments that looked like lenses began to emerge from the holes left behind by the floating stones.

More vibrations came from other places. The nine small pyramids around the main one were moving too. Instead of opening from the sides, their top popped open. The opening looked like a missile silo, it dilated open like an iris, and heavy crystal lens rose from below.

Praise to the sun and let the light dance.
