The twin Ruinous Powers of an adolescent-friendly editorial policy and Matt Ward's existence aside, there wasn't really that much to ruin lorewise from Rogue Trader's blatant rip-off homage to Frank Herbert's Dune meets Warhammer Fantasy in SPAAAAACE featuring:
SPAAAAACE Elves Eldar, SPAAAAACE Orcs Orks, SPAAAAACE Dwarves Squats, SPAAAACE Goblins Gretchin, SPAAAAACE Halflings Ratlings, SPAAAAACE Ogers Ogryn, SPAAAAACE pre-existing fantasty human product line Feudal Worlds, SPAAAAACE Skaven Hrud nobody knows, SPAAAAACE Beastmen (at some point), SPAAAAACE Slaan (they were already from SPAAAACE anyway), SPAAAAACE Zoats, and no SPAAAAACE Fimir whatsoever
