The Free-Trader's Guide was a service that the Lantillian Spacers' Brotherhood furnished. Core data within the guide was accessible to Brotherhood members who were in good standing, and additional capabilities could be unlocked for a small charge. The Brotherhood tried to confirm the data's reliability, but they did not ensure complete accuracy. Furthermore, they would not be held liable for any lost earnings or possible damages resulting from acting upon the Guide's data. A feature called "Trader's Gamble" was available in the Free-Trader's Guide, which notified eligible members of potentially profitable trading prospects. Typically, these marketplaces were situated in far-flung, hazardous, and disagreeable locales.
