The Harvester from Outer Space

From the publisher's website: Yves Geens (the author of Psychedelic Fantasies #3) has done it again. The Harvester from Outer Space is an adventure for mid-level characters that will warp your mind. It is set in a starship full of alien life-forms and high-tech gadgetry. "But I do not want high-tech in my fantasy setting!" Never fear. The starship is in orbit, thus allowing a referee to use it without having to introduce high-tech into his fantasy world. Compatible with every old school version of the original fantasy role-playing game.
