Oban is a mountainous planet and a human colony of the Unified Earth Government.[1]



After the Human-Covenant War, the United Nations Space Command discovered the planet and used it as a home for millions of human refugees.[2] Some of these refugees came from New Mombasa.[3] 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.[4] Operation: WHITE VAN also took place on the planet.[5] At some point before March 2558, the Insurrectionist Daniel Clayton acquired several AC-220 Vultures and AV-22 Sparrowhawks from a sale on Oban.[6]

Conflict on Oban[edit]

Main article: Battle of Oban

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 UNSC Infinity. 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 damage 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.[7]

The destruction caused by the Guardian.

Created crisis[edit]

On October 17, 2558,[8] a Forerunner Guardian on Oban was activated and sent to Genesis by the Created, inadvertently taking a UNSC Marine patrol along with it.[9] Oban, along with Conrad's Point, Ursa IV, Queen Anne VI, and Adelaide, was one of the first five colonies in a 72 hour period that saw such an event. The Guardian's activation caused widespread destruction and numerous causalities on the planet.[10]


Oban's vast continent of Saviron is home to a highlands region of mountains interspersed with high-altitude grassy terrain.[2] By late 2558, at least one large city was located on the planet before much of it was destroyed during the Guardian's activation.[10]



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