A GALACTIC MENAGERIE

“A warrior does not let a friend face danger alone.”

– Cadet Jay-Den Kraag

For 60 years, Star Trek™ has presented hundreds of beings and creatures as friends, foes, or challenges for main and supporting characters. The sheer variety of life-forms is an example of Infinite Diversity in Infinite Combinations (IDIC) and plays a key role in Star Trek’s storytelling themes.

This Allies and Adversaries Sourcebook enables Star Trek Adventures gamemasters to learn more about beings present in the Star Trek Galaxy and bring them to life in missions and campaigns.

Use this supplement to create, modify, and use interesting and cunning allies and adversaries, and collaboratively tell dramatic and engaging stories with your players, in your very own Star Trek-style episode or ongoing series!

The 128-page full-color, hardcover Allies and Adversaries Sourcebook features:

  • Guidance on NPCs and their uses, expanding on the content found in the core rulebook, as well as advice on using NPCs as allies, including ideas on balancing conflicts and encounters to give your crew challenging and satisfying experiences.
  • Information on many factions, including the Borg Collective, the Breen, the Cardassian Union, the Dominion, the Gorn Hegemony, the Orion Syndicate, the Klingon Empire, the Romulan Star Empire, the Tholians, and much more.
  • Game statistics for dozens of Minor, Notable, and Major NPCs among the various species and factions covered in this sourcebook.
  • Game statistics for a selection of creatures found throughout the Star Trek Galaxy, as well as rules and guidance on how to create your own original creatures for use in your missions and campaigns.

This second edition supplement is compatible with both first edition Star Trek Adventures and the Captain’s Log Solo RPG.

Nicholas ★★★★★

I was pleasantly surprised by the depth of the character profiles in this sourcebook, each one feels like a fully realized NPC. The detailed background hooks for the Klingon and Romulan adversaries are perfect for weaving into my ongoing campaign.

Amelia ★★★★★

Knew exactly what I was getting with this pre-order and the wait for late September is going to hurt, but the page makes the shipping timeline crystal clear so there are no surprises. The fact that it's a sourcebook full of allies and adversaries is exactly what my campaign needs to fill out the gal

Penelope D. ★★★★★

The sheer breadth of NPCs in this sourcebook is staggering—I’ve already used it to populate three separate missions without repeating a single officer. The layout makes it easy to flip to a faction’s roster mid-session, which saved my game when the crew went off-script.
