On the morning of [[2552#July|July 18, 2552]] Catherine got to have a brief talk with Admiral Stanforth concerning the [[Battle of Sigma Octanus IV|protracted battle]] that had just concluded at [[Sigma Octanus IV]].<ref name="HJ71852">''[[Dr. Halsey's personal journal]]'', ''July 18, 2552''</ref>  This followed the normal reporting on it and by the end of the day she had also read through both the admiral's after-action report on the battle (given to her by him) and the press releases put out by [[ONI Section Two|Section Two]].<ref name="HJ71852"/><ref name="HJ72052"/> Halsey's interest was piqued when she saw [[Jacob Keyes]]' name and that of his ship, the {{UNSCShip|Iroquois}}, featured prominently in the reporting, so she found herself skipping ahead to confirm he had survived.<ref name="HJ71852"/> In her journal she surmised that the maneuver being dubbed "the [[Keyes Loop]]" had been inspired by one of Admiral [[Preston Cole|Cole]]'s.

She was unsure why Spartans would have been committed there, seeing as the planet was in all probability about to be glassed at the time, but even [[Kalmiya]] was unable to break the section's encryption.

After more than six hours since his message Halsey had still received nothing, but she decided against second-guessing him and elected to simply continue waiting.<ref name="HJ72152"/>

By [[2552#August|August 24]] Doctor Halsey had been shown a [[hologram]] of a piece of [[Sigma Octanus IV artifact|an object]] [[Blue Team]] had recovered from Sigma Octanus IV—though she was not made aware of its point of origin or even what branch or group within ONI had seen fit to share it with her. This, of course, hindered her from performing a complete analysis. Even so, it was plain to her that the artifact shared many iconic language and code forms with the [[Forerunner]] [[Babd Catha Forerunner vessel|ship]] buried beneath SWORD Base. In her journal she puzzled over a possible connection between what she judged to be the more "standard" stylized [[Forerunner symbols|glyphs]] and took note of potential similarities between other glyphs and hypothesized navigational code found in Covenant transmissions. She ultimately could not draw a conclusion and even wondered if perhaps [[Illegal Entry Protocols|illegal entry protocol]] deconvolution was to blame. Halsey hypothesized at this time that the Forerunners might represent predecessors of the Covenant, if not a culture far more ancient and removed. She was unable to copy the data the hologram displayed and instead had to commit it to memory. Deciphering the message on the object would require actually having it and all relevant etiological data, so she shared this with her undisclosed ONI counterparts knowing it would get back to [[Colonel]] [[James Ackerson]]. She suspected it was in his possession and was sure she could get everything he had on it once he realized her help would be needed to decipher it.<ref name="HJ82452">''[[Dr. Halsey's personal journal]]'', ''August 24, 2552''</ref> At 0915 hours the next morning Halsey was fourteen minutes and eighteen seconds late to her private office within the Omega Wing of [[CASTLE Base]], as [[Déjà]] pointed out as soon as she entered.

In her journal, she surmised that Ackerson was unlikely to find anything of interest there and cynically expressed hope that he might cross paths with the enemy. Before NOBLE Team's arrival Catherine had a number of tasks which she was determined to make sure were accomplished.

In case something were to happen to her, Halsey recorded a purge code and its override failsafe password in her journal.<ref name="HJ83052"/>
 
Upon entering SWORD Base the surviving members of NOBLE were led at [[Cortana]]'s direction to a tram which would carry them one-and-a-half kilometers east and around two thousand feet underground, where Halsey was.<ref name="HRTP"/> Once the four of them had climbed aboard she appeared on a monitor and apologized to [[Carter-A259]] for the unusual security measures which had kept them from fully knowing what to expect at the base. He started to remark on the fact that she'd been listed as having died, but the doctor dismissed the casualty reports relating to her as false before he could finish and said she only wished the same could be said for the rest of his team, both [[Jorge-052]] and [[Kat-B320]] having been killed within the last few weeks. She offered what might have been a small comfort in sharing that the [[data module]] delivered by Kat had unlocked the secrets of her nearby [[Babd Catha Forerunner vessel|excavation]]. She then explained that their orders to destroy all sensitive material at the base had been overridden, as they had always been nothing more than a pretext to bring them to her so that they could take possession of this vital data and deliver it elsewhere.
