From publisher blurb: The Fontier Zone is the region of the galaxy with a patchwork of jurisdictions: small empires, planets with multiple governments, and diverse systems. It is the true home of the Bulldogs, full of danger and adventure. The core book describes only the basics of the region, but Ports of Call: The Frontier Zone adds multiple locations suitable for exploration. Written by Nathan Crowder, this supplement details diverse planets in the Frontier Zone. It gives material to continue to round out these locations in the galaxy and spur adventures within the Frontier Zone itself.
