<P> Lana and Lilly Wachowski, the creators of The Matrix franchise, instructed Fishburne to base his performance on Morpheus, a character in Neil Gaiman's comic book series The Sandman . At the studio's request, Gaiman later wrote "Goliath", a promotional short story set in the film's universe . </P> <P> The name Morpheus is that of the god of dreams in Greek mythology, which is consistent with the character's involvement with the "dreaming" of the Matrix . The mythical Morpheus and his family, including two brothers (Phobetor and Phantasos), lived in a dream world protected by the Gates of Morpheus with two monsters standing guard . Beyond the gates were the River of Forgetfulness, beside which Morpheus once carried his father to hide in a cave, and the River of Oblivion . This theme of duality carries over to Morpheus in The Matrix, who offers Neo either a blue pill (to forget about The Matrix and continue to live in the world of illusion) or a red pill (to enter the painful world of reality). </P> <P> In the Matrix films, Morpheus is the captain of the Nebuchadnezzar, which is a hovercraft of the human forces of the last human city, Zion, in a devastated world where most humans are grown by sentient machines and kept imprisoned in the Matrix, a virtual computer - generated world . Morpheus was once a human living inside the Matrix until he was freed . </P> <P> Morpheus is apparently a very popular public figure in the city of Zion . He is also known in the Matrix, but as a dangerous terrorist wanted by' Agents', who appear to be Federal investigators but are sentient computer programs that patrol the Matrix, eliminating any threat to the Matrix . </P>
