As we all know, working for the corporation is a hard life and the mission you are to be sent on this time is far from the usual run of the mill stuff. The back room boys have discovered a new dimension that contains a strange artificial world hanging in space.
Of course, they want it mapped and as Trainee Assistant Cartographer for Unknown Worlds, the job has fallen to you. Because of the Company's far from noble motivations (it's all government sponsored work you know), time is money. The more time you spend out there the more money the company can claim. The Remote Scout Craft you are given is an old fashioned Geographic Environmental Reconnaissance Land-Mapping Device, known as GERALD. The craft is expensive to maintain to your time is limited. If you do not move fast the mission will be terminated.
The ships computer holds the initial radar map of the surface and your task is to explore each area, collecting energy in the form of jewels, for which you will be rewarded with extra time.
Since this world is hung in the infinity of space, falling off is not a good idea. Should you lose or destroy your craft it will be re-created and beamed back to the last location visited, but this will cause an enormous power drain resulting in the loss of valuable time.
So there you have it - do a good job and the rewards will be great, otherwise... well, you don't want to be a Trainee Assistant Cartographer all your life - do you?
