Unlimited trade is possible this turn. With only one city, it's easy to find all your contacts. The player may take one good for free. A chance discovery is made while exploring an abandoned city. This oversized moon orbits a gas giant planet that radiates enough energy to give the moon a temperate climate.
Little energy arrives from the distant sun.
All devices not in a hold are damaged. A burst of radiation from the gas giant scrambles equipment. Navigating through a gas giant system has it's hazards. Place the ship on the spot above the city, and move it 1d6 along its previous course. Navigation is difficult in a complex system like this - the approach is missed.
