Lilith

Lilith, a mind trapped in a computer in the Boris chronicles, is first seen in Book 3, Revelations, as the companion of Gyada, the being who had been trapped in the cave for centuries, who escaped when the Siberian Base was developed, and the caves opened to exploration. She had bee entrapped there by Michael, as punishment.

Also in the cave was a mad Kurtherian scientist, who had crashed on Earth even before TOM. His name was Chaos Is In Limited Options, CILO (See characters, and he had tortured his AI, and theb Gyada, until theywere both insane. When Olaf and his people found her, because the computer being, because she was unable to communicate (spoke only Kurtherian, of a dialogue before TOM's time), and Gyada was also silent from fear, thet put it in a faraday cage, as a protection for all concerned.

While Lilith was a genius when it came to manipulating biology, she was far less capable when it came to physical and mechanical technologies. She could maintain their communication links and devices, but had not managed to replicate what TOM had achieved with the shuttlecraft. Nor did they have the capability to make use of the theory she knew. To be entirely fair, she didn’t have the industrial base to work with. TOM had access to far more when the shuttles were originally built.
