Delphi

"The secret army? Lying before a ? *Laughs* Honoured to deceive."

- Oracle, on the creation of Delta Company.

Oracle is a  who served as the resident AI for Delta Company. A result of the experimental LIBRARIAN Initiative, she was given to the Beta-5 Division's Director Jazmine Utah to act as her personal AI, though Oracle's duties to Delta Company meant she rarely operated as such. Much her predecessors, she acted as the technical expert in the base, training the Spartans in specialised hacking skills and co-teaching general knowledge. In other functions, she also ensured the secrecy of the Deltas, hunting down and corrupting spy programs attempting to access data around it.

After their activation, Oracle was utilised by the Spartans and the in operations as cyber-warfare support. Her ability to manipulate native firewalls and assimilate dumb AIs, as well as her substantial decryption skills, proved invaluable in recovering information for both the UNSC and the Beta-5 Division.
