The coordinates flashed on the screen: R0712.7z. It was a location deep in the unknown reaches of the galaxy, a sector shrouded in mystery and speculation.

"We have been waiting."

As the ship shuddered and lurched, the captain's thoughts turned to the rumors that had circulated about R0712.7z – whispers of an ancient alien city hidden beneath the planet's surface, of technology that defied understanding, and of an unquenchable hunger that lurked in the shadows.

"...Project Echo-12 abandoned...terrain anomalies detected... containment protocols engaged... Requesting backup..."

The captain's comms officer, Ensign Amy K'Rhyn, looked up from her console. "Captain, I'm picking up a faint energy signature from the coordinates. It's not natural."
