From the back of the book:
The planet is Mertactor/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, L.I.C., and return it to Baron Edkos Volentine, a corporate director. You've got two days before your passage 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.
"Gambit" is a term from chess, an ancient Solomani pastime, describing the early sacrifice of a pawn in exchange for a long-term positional advantage. Baron Edkos Volentine had many pawns on Mertactor to choose from, but guess who got the job?
Welcome to Mertactor.
