Thrall Intelligence

"It was a lucky shot really. Ion cannon hit the battlecruiser mid ship and the damage, explosive decompression, and electromagnetic fallout left the ship's crew mostly dead, and listing on emergency power. So ONI said we're doing a 'Fireaxe' missions, we go in, tear out anything shiny, and collect any intel, then scuttle it. Its all fine, minimal resistance. Then we get to the bridge. ONI says extract the AI, but we can't find anything except quantum computers on the bridge. We cut through a sealed bulkhead, and we find her. She was in a gel tank, and had so many cybernetics we had a hard time believing she was human at first. We pulled her out of there, and brought her back. DNA tests show she was snatched from some colony raid last year, and during that time to Demiurge had fitted her with enough cybernetics to turn her into a living computer. This was how they were closing the supposed "AI gap". By making god damn abominations"

The was a type of organic super computer developed by The Demiurge as an effort to close the technology gap in artificial intelligence between them and the UNSC. Using a 'wetware' component, an organic mind, they could create a machine that could close to the performance of a smart A.I. though falling just short of the raw processing power. The augmentations required to do this were extraordinarily invasive, and the strain placed on the organic component often burned them out after a few years in service, but ultimately, this cheap method allowed the Demiurge, and their successor states, to quickly equip their forces with A.I.s.
