Here a nifty free module I just discovered… North Battlement Sector. It’s is a free sector for the Terminal Space supplement to OD&D/Swords and Wizardry, written by Chris Robert.
A free sandbox for the Terminal Space supplement to OD&D. Sahuagin in space, Phase Spiders nesting in asteroid mines, and battered hulks infested with the undead. No Vulcans allowed.
