Margaret Parangosky

Admiral Margaret O. Parangosky (UNSCMID 03669271) was the director of the Office of Naval Intelligence.

Background
Born in 2461, Parangosky was described as short and aged, yet sharp and cold as ice female. Despite her withered appearance, she was very powerful and deadly: only one person had ever crossed her and lived, and Colonel James Ackerson considered her to be the most dangerous person in the UNSC. Parangosky was a Rear Admiral by 2511.

After the Battle of Groombridge-1830 in 2530, Admiral Preston Cole wrote down a proposed protocol procedure that would slow down the Covenant from finding Earth; secrecy. This proposal was approved by Parangosky and would become known as the Cole Protocol.

Restriction of Onyx
Late in her career, Margaret Parangosky restricted the planet, Onyx, from the rest of the UNSC after they discovered Forerunner ruins on the surface of the planet in 2511. She would return several times to check up on and report on the project, but it was eventually sidelined so funding could go elsewhere.

Spartan-III Project
In 2531, Parangosky was aboard the, where she attended a meeting with Rear Admiral Rich and Captain Gibson where Colonel James Ackerson would propose the SPARTAN-III project. Parangosky approved the creation of Alpha Company, and authorized a plan in which Lieutenant (Jr Grade) Kurt Ambrose would be abducted and put in charge of training the Spartan-III's.

In 2537, Parangosky was once again aboard the Point of No Return, to review the progress of the Spartan-III project and to authorize Beta Company, following the destruction of Alpha Company in Operation: PROMETHEUS.

Later Career
By 2552, Parangosky had risen to rank of Four Star Admiral, and she was named the head of the Office of Naval Intelligence. She continued working aboard the UNSC Point of No Return, green-lighting some of Humanity's most controversial projects.
