“One or more planets surround most stars, and every one of these worlds is utterly unique. All Starfleet personnel should keep in mind that each new world they encounter has the potential to be deadly and, at the same time, home to secrets found nowhere else.” – Star Trek Adventures Core Rulebook, Chapter 06.10, Strange New Worlds.
Any Star Trek game is going to have your teams encountering strange new worlds. Instead of having to rely on purely your imaginations, use the PlanetMaker tool to create the planets and moons where the action will take place!
