Mack

Personality
Mack is an overbearing A.I. on Harvest. His chosen avatar is that of a cowboy, exactly as those from spaghetti western movies. He is lighthearted and speaks in a southern drawl. He functions as a general control for every harvesting autonomous robotic devices known as JOTUNs. He worked adjacent to a separate AI responsible for the seven space elevators on Harvest known as the Tiara who was known as Sif.

Battle of Harvest
He often would playfully "flirt" with Sif, eliciting strange responses in the female AI, seemingly of hate but tinged with an unexplainable feeling analogous to human attraction underneath. Eventually he reveals to Sif that he is not one but two AI's, his counterpart being an AI known as Loki, the original ship AI of the first peoples to settle on Harvest. As the Covenant press their attack on the planet, he gives over his control to Loki, transmitting "himself" into the thousands of JOTUN machines below. He instructs Loki to keep Sif safe, but he disagrees and believes it to be easier just to destroy her. Mack eventually rebels against Loki, resisting his attempt to activate a ground-based Mass Cannon, which had the potential to cause severe harm to escaping refugees. Mack's final transmissions are extremely mysterious as the Covenant burn his world...he continues to resist, but as his resources dwindle he makes a last desperate attempt to help his now destroyed "love" Sif by burying her destroyed Space Elevators. He tries to "Bury your strands so deep their fires can't reach them \ \ and glass them like the rest". His final words are a misquoting of Shakespeare, a habit he had that annoyed Sif but created a bond between the two.
