Infinity returns to Requiem, where the Covenant—led by Jul 'Mdama, who styles himself as "the Didact's Hand"—and Prometheans are still active.Sarah Palmer, commander of the Spartan-IVs, deploys Spartan squads to Requiem's interior. Crimson Squad recovers a mysterious artifact being excavated by Covenant; Infinity scientist Doctor Glassman disappears after studying the device. Catherine Halsey is brought to Infinity due to her knowledge of Forerunner technology.She is kept under guard by marines and Spartans including Gabriel Thorne, who lost his family during the Didact's attack on New Phoenix. While studying the artifact, Halsey begins receiving messages on her computer from an anonymous sender. The source of the transmissions is revealed to be 'Mdama, who captures Glassman and forces him to work on a Forerunner device that supposedly contains the Librarian. Pursuing 'Mdama's troops, Crimson Squad recovers another artifact. When Halsey examines the device, it displays images Thorne recognizes as depicting New Phoenix. Lasky reveals to Halsey and the Spartans that the UNSC knows Prometheans are former humans. Approaching the artifact looking for answers, Thorne is teleported to Requiem and captured by Covenant. Palmer arrests Halsey for communicating with 'Mdama. Thorne escapes captivity outside 'Mdama's base, and escapes with Glassman; they are rescued by Majestic Squad. Halsey uses an override code to force Infinity's AI, Roland, to assist her. Seeking information withheld from her concerning the Librarian, Halsey learns that Master Chief is alive. Halsey contacts M'dama to try and strike a deal, as they both want to find the Librarian; Roland breaks free of Halsey's control and summons guards to apprehend Halsey. Lasky decides to place Halsey in cryogenic sleep to prevent further trouble, but Promethean forces invade Infinity, capture Halsey and teleport her to 'Mdama's base. Serin Osman, head of the Office of Naval Intelligence (ONI), orders Lasky to kill Halsey, however he is reluctant to do it. Palmer sets off to Requiem to execute Halsey; Lasky sends a message to Majestic Squad to intervene and rescue Halsey from 'Mdama. Halsey steps into the Forerunner device and makes contact with the Librarian. Librarian gives Halsey the two pieces of the "Janus Key", an instrument that provides the real-time location for every piece of Forerunner technology in the galaxy; Librarian instructs Halsey to use the key to advance humankind. Upon receiving the key, Halsey exits the device and 'Mdama steals one piece of it from her. Halsey passes the second piece to Thorne as Majestic Squad and Palmer arrive. Palmer wounds Halsey just before a Promethean teleports 'Mdama and Halsey from the base. Credits:. Production: AXIS. Director: Stuart Aitken. Written by: Stuart Aitken.
