Star Trek: Small World

STARFLEET CORPS OF ENGINEERS
The da Vinci 's latest mission involves bringing precious cargo to the Mu Arae system -- an entire world that, through a miraculous feat of engineering, is being stored in a small, pyramid-shaped box.

To make matters worse, the caretaker of the world is in critical condition in sickbay. The S. C. E. must figure out the secret of the planet-in-a-box before it's destroyedŠ
