From publisher blurb:
The Black Star Companion provides additional rules and information to help you tweak your Black Star games. This book is split into nine parts, as follows:
1. Vast is the introduction.
2. New Traits introduces Careers and Flaws, two new optional character traits you can use to give Heroes more depth.
3. New Talents includes a collection of new Archetype Talents, Gear Talents, and Inherent Talents.
4. New Archetypes offers two new Archetypes: the Fringer, a Discipline-based Archetype with no supernatural abilities, and the Psychic, a less spiritual alternative to the Mystic.
5. Optional Rules presents a number of optional rules that can be used to tweak the game to better suit your table, including rules to make the game more challenging and combat more dangerous, for those who want to turn space opera into hard sci-fi.
6. Advanced Vehicles offers a few additional vehicle rules and provides stats for a variety of new starships and vehicles.
7. Capital Ships provides rules and guidelines for dealing with these massive vessels in your games.
8. Expanded Galaxy includes various resources GMs can use when prepping or running their games. This includes rules for aliens, a rogues' gallery of foes, rules for handling wealth and commerce, and even a random world generator.
9. Clarifications answers a few common questions.
