Dwellers of the Forbidden City is an adventure module, or pre-packaged adventure booklet, ready for use by Dungeon Masters in the "Dungeons & Dragons" ("D&D") fantasy role-playing game.
 The adventure was first used as a module for tournament play at the 1980 Origins Game Fair, and was later published by TSR in 1981 for use with the first edition "Advanced Dungeons & Dragons" rules.
 The module was written by game designer David "Zeb" Cook, who partly ascribes his hiring by TSR to his work on this module.
 In the adventure, the characters are hired to find an object taken to a lost oriental-style city, which has been taken over by a cult of snake-worshipers, the yuan-ti, and their servants, the mongrelmen and tasloi.
 The module was ranked as the 13th greatest "Dungeons & Dragons" adventure of all time by "Dungeon" magazine for the 30th anniversary of the "Dungeons & Dragons" game in 2004.
In the field of astrology, generational planets are planets that affect an entire generation of people.
 The generational planets are the outer planets Uranus, Neptune, Pluto, Sedna, and Quaoar.
Alan Miranda is a previous BioWare employee, who had worked on "Dungeons & Dragons" titles like "Neverwinter Nights" and "".
 In 2003, he left BioWare to form his own company, Ossian Studios, with his wife Elizabeth Starr.
 Miranda approached BioWare joint CEO Greg Zeschuk in 2005 to discuss the possibility of Ossian developing a "premium module" for "Neverwinter Nights".
 Premium modules were adventures created for "Neverwinter Nights" by BioWare and other companies.
 BioWare had been given autonomy on the premium module process from the game's publisher, Atari, and Zeschuk approved Miranda's proposal.
 Miranda's initial draft of the project was a pirate-themed adventure in the Sword Coast, which happened to be the same idea that BioWare itself was creating a premium module for, "".
 Miranda revised the concept and chose the Western Heartlands as the setting.
 Ossian estimated that a module on par with other large games like "Kingmaker" would take four to five months.
 Pre-production on "Darkness over Daggerford" began in April 2005 and took a month and a half.
 Ossian went through five designers in this stage, none of whom worked out.
 Choosing a designer required much of the time allocated for pre-production, and to compensate Ossian developers immediately began creating the game, fleshing out details as they went.
 In May 2006, Atari cancelled the premium module program, with no warning to developers of the current projects.
 Miranda and his team decided to finish the game anyway, and in August 2006 it was released free of charge on IGN's Neverwinter Nights Vault.
Paul Wittich (c.1546 – 9 January 1586) was a German mathematician and astronomer whose Capellan geoheliocentric model, in which the inner planets Mercury and Venus orbit the sun but the outer planets Mars, Jupiter and Saturn orbit the Earth, may have directly inspired Tycho Brahe's more radically heliocentric geoheliocentric model in which all the 5 known primary planets orbited the Sun, which in turn orbited the stationary Earth.
A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.
 One spacecraft, Voyager 2, also visited Uranus and Neptune.
 The nine missions include two; Ulysses and New Horizons, whose primary objectives are not related to the outer planets, but which flew past Jupiter to gain gravity assists en route to a polar orbit around the Sun, and Pluto—at the time of its launch considered an outer planet—respectively.
 Cassini–Huygens also flew past Jupiter for a gravity assist on its mission to explore Saturn.
The Nice 2 model is a model of the early evolution of the Solar System.
 The Nice 2 model resembles the original Nice model in that a late instability of the outer Solar System results in gravitational encounters between planets, the disruption of an outer planetesimal disk, and the migrations of the outer planets to new orbits.
 However, the Nice 2 model differs in its initial conditions and in the mechanism for triggering the late instability.
 These changes reflect the analysis of the orbital evolution of the outer Solar System during the gas disk phase and the inclusion of gravitational interactions between planetesimals in the outer disk into the model.

Tale of the Outer Planes is an adventure module for the "Dungeons & Dragons" fantasy role-playing game, set in that game's Outer Planes.
 TSR, Inc. published the module in 1988 for the "Advanced Dungeons & Dragons" rules.
 The module is a collection of adventures designed by Deborah A. Christian, Vince Garcia, Thomas M. Kane, David and Martha Ladyman, Christopher Mortika, John Nephew, Bruce Nesmith, Bill Slavicsek, Rick Swan, John Terra, and Ray Winninger.
 Its cover art is by Jeff Easley.
 Its interior art is by Chris Miller and Jeff Easley, and cartography by Dave LaForce.
A transit of a minor planet takes place when a minor planet passes directly between an observer and another heavenly body, obscuring a small part of that body's disc.
 From the perspective of observers on Earth, transits of the Sun and Moon by minor planets are very rare, as the minor planets orbiting between the Earth and those bodies are few and very small.
 Transits of the Sun would be more visible from the outer planets.
Rob Donoghue is a game designer who has worked primarily on role-playing games. Together with Fred Hicks he created the "Fate system" and has been designer or lead designer of numerous award winning role playing games.
 He was a lead designer of the role-playing games "Spirit of the Century" and a designer of "The Dresden Files Roleplaying Game", and has also worked closely with Cam Banks on the Cortex Plus games, a lead designer for "", and as a designer for "Marvel Heroic Roleplaying".
 He has also contributed to "Dungeons & Dragons" 4e.
