From publisher blurb: Darkmantle Space Freighter is a Fifth Edition plug-in adventure for four characters with an average party level (APL) of 1, 3, 5, or 8. This document offers details for each level and makes adjustments accordingly. The characters are transported into the far reaches of outerspace (or your campaign’s fantasy equivalent) to a seemingly unoccupied space freighter. They soon learn that they aren’t alone, but surrounded by dangerous aberrations.
