Random Encounters

Source Galaxy Exploration Manual pg. 39
Whenever PCs explore, there’s a chance for a random encounter; this chance is based on the relative population density of an area, with some types of terrain tending to be denser than others. Each time the PCs travel or recon, roll a d20. On a roll equal to or higher than the encounter DC listed in the Hexploration Table (see below), a random encounter occurs. The GM can adjust these numbers based on circumstance.
The GM can use the inhabitants and adventure hooks tables in the corresponding biome section (pages 48–95) to inspire a random encounter. Remember that encounters can be far more than combat with wandering monsters; there are plenty of opportunities for roleplaying and social encounters, especially those that tie into and expand on a world’s adventure hooks or various other attributes.
