Skirmish at Librarian's Rest

"Majestic, I have a personal favor to ask. Doctor Halsey has been abducted."

- Captain Thomas Lasky

The Skirmish at Librarian's Rest was an engagement during the Requiem Campaign taking place at "Librarian's Rest" when Spartan Commander Sarah Palmer attempted to assassinate Doctor Catherine Halsey and Fireteam Majestic attempted to rescue her.

Prelude
During the early stages of the Requiem Campaign, at the location known as "the Cauldron," Spartan Fireteam Crimson recovered a mysterious artifact which sucked in Doctor Henry Glassman when he accessed it aboard the. Subsequently, Doctor Catherine Halsey was brought aboard where she determined that the artifact was communicating information from the ship to Requiem.

As Halsey later attempted to understand the artifact, Jul 'Mdama utilized it to contact Halsey via her data pad to entice her into helping him, offering Halsey the truth about a great many things, including the Prometheans. As proof, Jul ensured that Fireteam Crimson retrieved "the Didact's Gift," a Durance containing the "soul" of a Promethean Knight who was originally a human digitized by the Composer during the New Phoenix Incident. Having provided proof, Jul further enticed Halsey by mentioning the Librarian, but Commander Sarah Palmer noticed Halsey's suspicious behavior and Captain Thomas Lasky had her arrested. However, Halsey subsequently escaped using an override code on Infinity's AI Roland and made contact with Jul whose identity she quickly deduced. Halsey offered Jul her help with the Librarian, but the communication was cut off by Roland who regained control of himself and alerted the ship's crew to Halsey's actions. Jul subsequently launched an invasion of the ship that ended with a Promethean Knight abducting Halsey.

On Requiem, Halsey was brought to "Librarian's Rest" where she was able to deactivate the protective shield that Glassman had inadvertently activated and enter the shrine containing the Librarian's imprint. In the shrine, Halsey met with the Librarian herself who provided Halsey with the Janus Key, a Forerunner artifact that provided the real-time location of all Forerunner technology in the galaxy. The Librarian warned that Requiem's time was almost at an end and ordered Halsey to take the Janus Key to the Absolute Record before sending her back to "Librarian's Rest."

After being alerted of the situation, Rear Admiral Serin Osman ordered Lasky to eliminate Halsey. Despite Lasky's objections, Palmer deployed to Requiem to carry out the assassination while Lasky contacted Fireteam Majestic, who had just delivered a rescued Glassman to a Pelican and asked them to rescue Halsey.
