Greetings, Traveler. You've been recruited by Stargate Command (SGC) to defend the galaxy against the Goa'uld System Lords. Stationed at the secret Phoenix Site, you now embark upon your training within the Stargate program. Each adventure through the Stargate opens a journey to known and unknown worlds where the future of civilizations may be decided. Your decision to join our cause is greatly appreciated by the Tau'ri and the people of the Milky Way galaxy. This Core Rulebook will serve as your guide. Use it to aid in your training for our explorations and in battles to come. The Stargate SG-1 Roleplaying Game is a sci-fi tabletop game where you assume the role of a member of Stargate Command. As an SG team member, you and your teammates will go on missions, guided by a Gatemaster, in the fight against the Goa'uld and other threats. The game is based on the D&D 5th Edition Open Gaming License.
