Question: Ta-er al-Sahfer is a character in what universe?

<P0-S0> Richard Rory is a fictional character in the Marvel Universe. <P0-S1>  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. <P0-S2>  He was introduced in "Man-Thing" Volume 1, #2, a bit of a loner who rather easily befriended the nearly mindless monster. <P0-S3>  When in rural areas, he was frequently belittled for having a college education and a rather left-wing perspective. <P0-S4>  Later, under the pen of David Anthony Kraft, he became friends with She-Hulk, with slight romantic overtones that went nowhere. <P0-S5>  The character is named after Richard Cory, a nearly opposite character whose song was playing on the radio when Gerber created the character. <SEP> <P1-S0> Isis is a DC Comics superhero, as well as a separate Egyptian goddess also living in the DC Universe. <P1-S1>  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! <P1-S2> /Isis Hour". <P1-S3>  The television character appeared in several late 1970s DC Comics publications. <P1-S4>  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!" <P1-S5>  family of characters. <P1-S6>  The Egyptian goddess character has been depicted within the "Wonder Woman" comic book. <SEP> <P2-S0>  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. <P2-S1>  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. <P2-S2>  Russell Tovey stars as Ray Terrill / The Ray. <P2-S3> 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. <SEP> <P3-S0>  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. <P3-S1>  Originally portrayed by Jacqueline MacInnes Wood in "Arrow"'s pilot, she has been portrayed by Caity Lotz since the second season. <P3-S2> 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. <P3-S3>  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".
