Star Trek Adventures - Mission Briefs: Trade Ledgers
Star Trek Adventures - Mission Briefs: Trade Ledgers, subtitled Tales from The Next Generation Era, is a set of ten mission briefs for the  role playing game.

Summary
Blurb
Starfleet isn't the only organization exploring the cosmos and warping from system to system. The Galaxy is full of independent trader crews, smuggling rings, mercenary groups, and more, most of which do not share Starfleet values or Federation ethos. During their tours of duty, Starfleet crews must be prepared to encounter any number of ruthless and cunning adversaries.

This packet presents ten detailed mission briefs oriented around encountering independent merchants and smugglers, each of which you can modify for use in your Star Trek Adventures campaigns set during The Next Generation (approximately 2360-2379) or any other era of play with minor modifications. Each mission brief is designed to stand alone, though they could be strung together into a story arc or added to an existing campaign.
