From the game's packaging:

"The planet is Mrtactor/District 268 of the Spinward Marches, located at the fringe of the Imperium. The assignment is simple and profitable -- recover a flashy artifact recently taken from a representative of DerBonne Merchants, LIC, and return it to home, the Far Trader "Arax House", is loaded with cargo and ready to leave. There's not really enough time, but it couldn't hurt to look around -- the Mertactor outback is supposed to be fairly scenic, and you might get lucky. Baron Volentine could be a useful man to make happy.

Star Crystal is a solitaire text adventure series based on the Traveller science fiction role-playing game system."
