Core 5

Core 5 is a section of HIGHCOM Facility Bravo-6 in Sydney, Earth. It is known to contain Margaret O. Parangosky's office, and appears to contain Serin Osman's office as well, the two connected by a corridor. Osman's office is known to contain an oak book case which held an ancient copy of The Admiralty Manual of Seamanship Volume II, a gift from Lord Hood to Captain Osman.

History
On January 26, 2553, the AI Black-Box was first introduced to Osman here, with the two meeting with Parangosky to discuss Osman's mission.
