Discovery Set 2 is here in digital and print! - Discovery Set 2 PDF Discount Code

Nine New Planet Traits for your adventures. Galaxy Builder Decks is a system-neutral card-based settings generator but was built with Traveller in mind. Draw planet cards and place them down to form a star system. Draw planet traits to customize each world with encounters, strange attributes, and dangerous creature behaviors. Draw star system cards to find local conflicts, employers, mission types. It's all about the visuals and the choices. I wanted to create something that helped with worldbuilding in any game and looked good on the table.

Some of the cards in this new expansion set:

• Double Planet - This planet has a twin companion. Were they formed at the same time, did something smash apart the original planet into two, or did someone move it there? Roll on the included tables to find out.
• Gravity Distortions - This area affects ship systems in a nasty way. What causes it? A blackhole, a local unstable star, or some unknown anomaly? Roll to discover the source and how it's messing up your vessel.
• Parasites - This planet is infested with parasites. They get in your skin, in your head, in your abdomen, and then? Well, maybe they just wanted a warm safe place to sleep...yeah, no, they want to use you as food or make a baby. Roll to pick your fate.
• Then there's Hibernation, Rapid Evolution, Implanted Population, Astrogation Shortcut, Void Zone, and Ancient Sites.

Freebies

• Free Pack Collection - includes twelve free samples of worlds, stellar objects, and planet traits.
