OSR Campaign Setting - Leigh Brackett Solar System Campaign Framework & D100 artifacts and treasures table for the Leigh Brackett solar system

 In Leigh Brackett’s "Old Solar System," science is indistinguishable from ancient magic, Mars is a dying desert of decaying stone cities and ancient secrets, Venus is a mist-choked swamp of matriarchal cults and sea-monsters, Mercury is a brutal rock of twilight nomads and penal camps, and Earth is a mercenary corporate force plundering the universe. We pick right up from OSR Campaign Setting - Leigh Brackett Solar System Campaign Framework For OSR Rpg Systems
