Question: Forsaken House is a fantasy novel that was written by an Author who has worked on which campaign settings?
Context: The flexibility of the "Dungeons & Dragons" ("D&D") game rules means that Dungeon Masters (DM) are free to create their own fantasy campaign settings. For those who wanted a pre-packaged setting in which to play, TSR, Wizards of the Coast (WotC), and other publishers have created many settings in which "D&D" games can be based; of these, the "Forgotten Realms", an epic fantasy world, has been one of the most successful and critically acclaimed settings.  Many campaign settings include standard sword and sorcery environments, while others borrow Oriental, Central American, swashbuckling, horror and even space-travel themes. Forsaken House is a 2004 fantasy novel by Richard Baker, set in the "Dungeons & Dragons" Forgotten Realms fictional universe.  It is the first novel in the "Last Mythal" series. In numerous campaign settings of the "Dungeons & Dragons" ("D&D") fantasy role-playing game, dinosaurs, based upon the actual-life reptiles of prehistoric ages, are present.  Some of the dinosaurs used in "D&D", such as "Triceratops", "Tyrannosaurus rex", and "Ankylosaurus", are real ones which used to exist on earth.  Others, such as the Bloodstriker, Fleshraker, and Swindlespitter from the Monster Manual III, though labeled as dinosaurs, are made up, and as such are likely better regarded as monsters.  Most D&D settings have a location where dinosaurs are known to dwell, and seeing as they coexist with intelligent races, they are sometimes depicted as tamed, with armored tyrannosaurs being used in battle and raptors used as mounts. In the "Dungeons & Dragons" fantasy role-playing game, the thri-kreen, or "mantis warriors", are an insect-like monstrous humanoid race.  Thri-kreen are one of the primary player character races of the "Dark Sun" campaign setting, and have also appeared in the "Spelljammer" and "Forgotten Realms" campaign settings, as well as the "Dungeons & Dragons v3.5" "Monster Manual II", the 4.0 "Monster Manual 3" and the "Monster Manual" for "Dungeons and Dragons 5th edition". Forsaken House is a play written by Wilfrido Maria Guerrero, published in his "13 Plays" (1947). Richard Baker (full name L. Richard Baker III) is an American author and game designer who has worked on many "Dungeons & Dragons" campaign settings. A campaign setting is usually a fictional world which serves as a setting for a role-playing game or wargame campaign.  A "campaign" is a series of individual adventures, and a "campaign setting" is the world in which such adventures and campaigns take place.  Usually a campaign setting is designed for a specific game (such as the "Forgotten Realms" setting for "Dungeons & Dragons") or a specific genre of game (such as Medieval fantasy, or outer space/science fiction adventure).  There are numerous campaign settings available both in print and online.  In addition to published campaign settings available for purchase, many game masters create their own settings, often referred to as "homebrew" settings or worlds. Jeff Grubb (born August 27, 1957) is an author of novels, short stories, and comics and a computer and role-playing game designer in the fantasy genre.  Grubb worked on the "Dragonlance" campaign setting under Tracy Hickman, and the "Forgotten Realms" setting with Ed Greenwood.  His written works include "The Finder's Stone Trilogy", the "Spelljammer" and "Jakandor" campaign settings and contributions to "Dragonlance" and the computer game "Guild Wars Nightfall" (2006). Oriental Adventures (abbreviated OA) is the title shared by two hardback rulebooks published for different versions of the "Dungeons & Dragons" ("D&D") fantasy roleplaying game.  Each version of "Oriental Adventures" provides rules for adapting its respective version of "D&D" for use in campaign settings based on the Far East, rather than the medieval Europe-setting assumed by most "D&D" books.  Both versions of "Oriental Adventures" include example campaign settings. A dwarf, in the "Dungeons & Dragons" ("D&D") fantasy roleplaying game, is a humanoid race, one of the primary races available for player characters.  The idea for the "D&D" dwarf comes from European mythologies and J. R. R. Tolkien's novel "The Lord of the Rings" (1954-1955), and has been used in "D&D" and its predecessor "Chainmail" since the early 1970s.  Variations from the standard dwarf archetype of a short and stout demihuman are commonly called subraces, of which there are more than a dozen across many different rule sets and campaign settings.
