Seoba is the third moon of Biko. A small and largely uninhabited moon, it was the site of a battle during the early Human-Covenant War.

History

Colonisation

Prior to 2424, Seoba was colonized and played an instrumental role in the terraforming of Biko. The Bikon colonists established a large ice quarry on the surface of the moon, using a mass driver running up a mountain on the surface to launch payloads of steel-encapsulated ice towards Biko to increase the planet's humidity. By 2424, the planet was capable of supplying its own rain and the quarry facility was largely abandoned, with ice building up in the now-defunct mass driver facility.

Human-Covenant War

Main article: Battle of Seoba

In 2526, the old Seoban ice quarry became the site of a heated battle between forces of the UNSC's Task Force Yama and an Insurrectionist coalition consisting of forces from the United Rebel Front, Biko Independence Army and Gao Liberation Force, among others. The Insurrectionist coalition had set up a staging ground in the ice quarry in preparation for a coup on the Bikon Chancellor, intending to take control of Biko and offer assistance to the Covenant in return for ensuring the continued survival of the planet. An insurrectionist plot had alerted the Covenant to their presence on Seoba and invited them to meet there, with the Insurrectionist fortifying the site with bunkers, M41 Vulcan rotary cannons and a fleet of Civet AFVs.

As part of Operation: SILENT STORM, Task Force Yama had independently picked the ice quarry as a staging ground for their operation, intending to hide their fleet of Razor-class prowlers in the quarry to strike the Covenant Fleet of Inexorable Obedience while they were distracted. On March 18, the task force emerged from slipspace to discover the rebel base, and consequently prepared to assault the base, as it was critical to the success of SILENT STORM. The resulting battle saw the deaths of dozens of ODST personnel and the destruction of one of the Prowlers, but the UNSC did succeed in capturing the ice quarry and the remaining rebels there.

Shortly after, the Covenant Bloodstar Flotilla arrived at Seoba to meet with the insurrectionists, only to discover the UNSC prowler force evacuating the planet. They began to fire on Seoba, but were ultimately repelled long enough for Task Force Yama to escape.

Topography

Seoba had a gravitational pull roughly one-eighth that of Earth's. The moon had a trace atmosphere, but the atmosphere was too thin to carry sound or kinetic energy. The moon was largely composed of ice, and had a milky-white surface when viewed from orbit.
