Title: Golden Archer
Passage: Golden Archer (Wyatt McDonald) is a fictional superhero appearing in American comic books published by Marvel Comics.  A member of the Squadron Supreme, the character exists in the universe of that team, an alternate universe to Marvel's main shared universe, the Marvel Universe.  He has also gone by the codenames "Hawkeye" and "Black Archer".
Title: Marvel Cinematic Universe
Passage: The Marvel Cinematic Universe (MCU) is an American media franchise and shared universe that is centered on a series of superhero films, independently produced by Marvel Studios and based on characters that appear in American comic books published by Marvel Comics.  The franchise has expanded to include comic books, short films, television series, and digital series.  The shared universe, much like the original Marvel Universe in comic books, was established by crossing over common plot elements, settings, cast, and characters.  Phil Coulson, portrayed by Clark Gregg, is an original character to the MCU and the only character to appear across all the different media of the MCU.
Title: Richard Rory
Passage: Richard Rory is a fictional character in the Marvel Universe.  He initially was a sort of author surrogate or alter ego for writer Steve Gerber, though Gerber is also shown to exist in the Marvel Universe.  He was introduced in "Man-Thing" Volume 1, #2, a bit of a loner who rather easily befriended the nearly mindless monster.  When in rural areas, he was frequently belittled for having a college education and a rather left-wing perspective.  Later, under the pen of David Anthony Kraft, he became friends with She-Hulk, with slight romantic overtones that went nowhere.  The character is named after Richard Cory, a nearly opposite character whose song was playing on the radio when Gerber created the character.
Title: Sara Lance
Passage: Sara Lance, also known as the White Canary, is a fictional character in the television series "Arrow", which is based on the DC Comics superhero Green Arrow.  The character was created specifically for television by Greg Berlanti, Marc Guggenheim and Andrew Kreisberg, but incorporates character and plot elements of the Black Canary, a DC Comics superhero.  Originally portrayed by Jacqueline MacInnes Wood in "Arrow"'s pilot, she has been portrayed by Caity Lotz since the second season.  She initially fights in "Arrow" under the moniker of "The Canary," translated from her Arabic League of Assassins name "Ta-er al-Sahfer" (Yellow Bird), and later adopts the codename White Canary on the "Arrow" spin-off "Legends of Tomorrow".
Title: Donald Duck universe
Passage: The Donald Duck universe is a fictional shared universe which is the setting of stories involving Disney cartoon character Donald Duck, as well as Daisy Duck, Huey, Dewey, and Louie, Scrooge McDuck, and many other characters.  The world is a part of the Mickey Mouse universe, but is more detailed.  Life in the Donald Duck universe centers on the city of Duckburg, usually located in the fictional U.S. state of Calisota, analogous to Northern California.  The world also incorporates several other real and fictional locations, as well as historical figures and a fictional timeline, which is followed with varying degrees of consistency.
Title: Isis (DC Comics)
Passage: Isis is a DC Comics superhero, as well as a separate Egyptian goddess also living in the DC Universe.  The recent superhero character is modeled closely after the main character of "The Secrets of Isis", a live-action American Saturday morning television program that served as the second half of "The Shazam! /Isis Hour".  The television character appeared in several late 1970s DC Comics publications.  The more recent superhero character was introduced into the DC Universe in 2006 as a female counterpart to the character Black Adam, a part of the "Shazam!"  family of characters.  The Egyptian goddess character has been depicted within the "Wonder Woman" comic book.
Title: Arrowverse
Passage: The Arrowverse is a shared fictional universe that is centered on television series airing on The CW, developed by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg, Phil Klemmer, and Geoff Johns, based on characters appearing in publications by DC Comics.  The shared universe, much like the DC Universe in comic books or the cinematic DC Extended Universe, was established by crossing over common plot elements, settings, cast, and characters.  The Arrowverse stars Stephen Amell as Oliver Queen / Green Arrow, Grant Gustin as Barry Allen / Flash, Megalyn Echikunwoke as Mari Jiwe McCabe / Vixen, with an ensemble cast leading "Legends of Tomorrow", including Arthur Darvill as Rip Hunter, Caity Lotz as Sara Lance / White Canary, Brandon Routh as Ray Palmer / Atom, Dominic Purcell as Mick Rory / Heat Wave, with Victor Garber and Franz Drameh as Martin Stein & Jefferson "Jax" Jackson / Firestorm.

Title: Dance Dance Revolution Universe 2
Passage: Dance Dance Revolution Universe 2, sometimes abbreviated as Universe 2, is a music video game for the North American Xbox 360.  Released by Konami Digital Entertainment on December 4, 2007, "Universe 2" is a sequel to "Dance Dance Revolution Universe" released earlier the same year.  "Universe 2" features a large soundtrack with songs ranging from the 1970s to today, new modes of gameplay designed for newcomers including Freestyle Mode which allows players to dance without needing to step on any arrows, Quest Mode where players build a dancing character and travel from location to location in a virtual world facing off against other dancers, and downloadable content through the Xbox Live service.  The game was released in Europe with a different set of songs as "Dancing Stage Universe 2".
Title: List of dimensions of the Discworld
Passage: Discworld, the fictional planet of a fantasy series by Terry Pratchett, exists at a point near the very edge of universe's reality spectrum.  From here, the fabric of the fictional universe's reality is gossamer-thin, and excessive pushing can and often does break holes into other, often far less hospitable, domains.  The most dangerous of these domains are the Dungeon Dimensions, a region beyond the narrative's reality itself, whose inhabitants (inspired by the formless horrors of H. P. Lovecraft) wait to swamp our reality with all the force "of an ocean warming itself against a candle".  A number of minor fictional universes attach themselves tangentially to the Discworld universe, particularly Death's Domain, the home of the Disc's Grim Reaper, from which he descends to do his job, and the parasite universe of Fairyland, home of the sociopathic and vicious Elves.  Additionally, the Dark Desert is a region that, according to the Discworld's Omnian religion, souls cross to pass into the next world.  The Discworld character Death frequently takes souls here, and in recent books, it seems to have become the afterlife of choice for most Discworld characters, not just Omnians.
Title: All-American (comics)
Passage: All-American (Jack Magniconte), who has also been called Mr. Magnificent is a fictional character published in the New Universe imprint of Marvel Comics.  He was the central figure of "Kickers, Inc.", and when that title was discontinued he became a supporting character in other New Universe titles.
