Oban

Oban is a mountainous human colony.

History
After the Human-Covenant War, the UNSC discovered the planet and used it as a home for millions of human refugees. The UNSC Navy maintained a presence on the planet, using it as a staging ground for a number of highly classified military exercises, including Operation: DAYBREAK, located in the highlands of Saviron.

On July 16, 2558, the planet was attacked by Jul 'Mdama's Covenant and his Promethean allies. The attack was advocated by Doctor Catherine Halsey, who believed that a bold move would attract. As Halsey predicted, Infinity was deployed to the planet and Commander Sarah Palmer led a joint Spartan-UNSC Marine operation in response to the attack. The UNSC eventually repelled the attack, and only minor damaged was inflicted upon a new power station halting the colonization of the planet. However, Jul's Covenant attacked Oban just to lead Infinity into a trap.

A new, much more durable type of Promethean Knight was encountered on Oban during the attack.

Trivia
It is likely the planet is named after the Scottish town Oban.
