From publisher blurb:
Explore the dark corners of the Starjammer universe and uncover even darker secrets! These races, hidden until now, lurking in the deepest reaches of the galaxy waiting to befriend or terrorize, you and your crew.
Which will it be?
11 detailed races are presented for the Starjammer Core Rules, but can easily be adapted to other d20 based roleplaying games.
Which will you encounter first?
The robotic Angothians or perhaps the vulture-like Skrraaak?
These creatures and more await you in Black Codex: Alien Catalog Entry 1 from d20pfsrd.com Publishing!
