A ScienceFiction and {{Fantasy}} author and TabletopRPG gamer, Margaret Edith Weis (born March 16, 1948) is most famous for partnering with Creator/TracyHickman to create the ''Literature/{{Dragonlance}}'' setting and novels for ''TabletopGame/DungeonsAndDragons''. Pyramid Magazine claims that she and Hickman are entirely responsible for the entire gaming-fiction genre. This makes them pioneering auteurs or a pair of overblown FanFiction writers / [[PromotedFanboy Promoted Fanpersons]].

Weis, whether with Hickman, her second husband Don Perrin or solo, has also generated a large number of original intellectual properties, such as ''Literature/TheDarkswordTrilogy'', ''Literature/{{Dragonvarld}}'', the excellent and underrated ''Literature/RoseOfTheProphet'' trilogy, ''Literature/TheStarOfTheGuardians'' & ''Mag Force 7'', and ''Literature/TheDeathGateCycle''. She writes in a distinct style, preferring tense, telegraphic phrases, and her roots in RPG storytelling are generally obvious (''Death Gate'' doesn't go ''quite'' as far as instituting Magic Points, but the idea is evident). An eccentric [[BreakingTheFourthWall Fourth-Wall Breaker]], "Fizban" (or [[SignificantAnagram anagrams thereof]]), has appeared in several of her settings after originating in ''Dragonlance''.

Weis also owns two tabletop-RPG publishing houses. One, Sovereign Press, was founded to publish ''Literature/TheSovereignStone'' and handled ''Dragonlance'' on license for the ''TabletopGame/DungeonsAndDragons'' 3.5 ruleset from Creator/WizardsOfTheCoast; the other, Margaret Weis Productions, publishes the ''Series/{{Battlestar Galactica|2003}}'' (re-imagined), ''Series/{{Supernatural}}'' and ''Series/{{Firefly}}'' {{RPG}}s, as well as several smaller [=IPs=].

Currently working on a new six-book HighFantasy epic with TracyHickman, ''Dragonships''.
