the Mission

After a spelunking accident, Dorian finds himself trapped beside an underground stream, cold, soaked, and alone in the dark. Trying to overcome a bout of amnesia - brought on by several blows to the head while being carried deep - he pieces together what has happened and sorts out the bits of reality from the very weird dreams he's been having in solitary.

He finds some driftwood and attempts to make a fire only to discover he is not alone. There is a rather large space ship in the cavern with him. And the robot on board tells him it was his ship that landed here many millennia ago.

Discovering the mission he had been sent here on and more about those that set out to thwart its completion, he finds a way out of the cavern and gets back to the reason that brought him here so many, many years ago.
