We have deciphered a handful of Covenant transmissions that refer to—” She paused, checking notes on the data screen in her glasses. “—Ah, yes. ‘Prophets.’ We believe that these Prophets are in fact the leadership caste, and that they are viewed by the Covenant rank and file with an almost religious reverence.”
Dr. Halsey removed her glasses. “This is where you come in. Your mission will involve these so-called Prophets, and will be executed in four phases.
“Phase one. You will engage the Covenant and sufficiently disable, but not destroy, one of their ships.” She turned to face Captain Keyes. “I leave that in the capable hands of Captain Keyes and his newly refitted ship, the Pillar of Autumn .”
Captain Keyes acknowledged her compliment with a curt nod. He tapped the stem of his pipe on his lips thoughtfully.
The Master Chief was unaware of any Covenant ship ever being captured. He had read the reports of Captain Keyes’ actions at Sigma Octanus IV . . . and considered the odds of actually capturing a Covenant vessel. Even for a Spartan, it would be a difficult mission.
“Phase two,” Dr. Halsey said. “Spartans will board the disabled Covenant ship—neutralize the crew, and crack their navigation database. We will do precisely what they have been trying to do to us: find the location of their home world.”
