SPACE... THE FINAL FRONTIER

“Risk is our business. That’s what this starship is all about. That’s why we’re aboard her.”

– Captain James T. Kirk

The 23rd century serves as the foundation of the entire Star Trek universe. A time in which many of the most iconic people, starships, and locations are introduced, and when many of its key events take place.

The 23rd Century Campaign Guide presents the entire 23rd century for you to use in the Star Trek Adventures roleplaying game, from the growing pains of the nascent Federation in the century’s early decades to the rising tensions with the Klingon Empire that sparked a brutal war in 2256-2257. Then, onward into the bold “five year missions” period and the volatile latter third of the century.

Characters of every department, from command to medical, can use new rules and character options to deepen their gameplay experience. No matter the composition of your crew, this guide provides the means for you to play through some of the most dramatic and influential periods in Star Trek! 

How does your crew fit into this iconic era and what trailblazing stories of their own will they tell?
