Kamchatka

Kamchatka, also known as Caspar V, is the fifth planet in the Caspar system. A remote planet, Kamchatka was created by the Forerunners and served as a node of the Domain for the ecumene. Following the firing of the Halo Array, Kamchatka remained an obscure world at the fringes of civilization until the planet's discovery in 2558.

History
Kamchatka was a product of Forerunner astroengineering, created to serve as a link to the Domain—the Forerunner knowledge network. Though the planet has an unusual lack of various structures and facilities located on its surface, Kamchatka has many structures buried under its snow and ice, including a communications hub. The Stormbreak mountain range, considered to be "the broken spine" of Kamchatka, was mended by the Forerunners.

In 2558, a communications hub on the planet activated, attracting the attention of both the United Nations Space Command and Jul 'Mdama's Covenant. The Covenant established an outpost on Kamchatka, concentrating a bulk of their forces on the planet while they attempted to access the planet's data network. While Doctor Catherine Halsey and Jul 'Mdama worked to access the network at a large Forerunner structure, Halsey discovered information relating to the recent attacks by Guardians on human colonies. Additionally, the Covenant managed to locate a Guardian on Kamchatka. Halsey contacted and warned the UNSC, and in response Expeditionary Strike Group 1 was deployed to Kamchatka as part of Operation: ANCHORITE to assault the Covenant staging area. During the battle, Fireteam Osiris was tasked with assassinating 'Mdama and retrieving Halsey. Osiris was deployed to the surface of the planet, as Jul 'Mdama's Covenant forces battled the rebelling Prometheans. As Osiris fought their way to the structure, they assassinated 'Mdama and brought Halsey back to, which soon left the system.

Some time after the battle, the UNSC intended to establish a military complex and power station on Kamchatka to control the planet's Forerunner sites. While the UNSC is aware of the Forerunner structures under Kamchatka's surface, no detailed surveys have been conducted to observe them as of 2558. As she formed the Created, Cortana activated the Guardian on Kamchatka.

Topography
Kamchatka is ostensibly an unremarkable and barely habitable arctic world, underdeveloped and home to a frigid climate, with temperatures ranging between -87 °C to -12 °C (-125 °F to 10 °F). The terrestrial planet's surface is rugged, with a majority of the surface covered by ice and snow. However, closer analysis has revealed evidence of extensive mega-engineering of the planet by the Forerunners. While much of the larger Forerunner structures are buried under the snow and ice, the Stormbreak mountain range is an expansive mountainous region called the "broken spine of Kamchatka”, said to be mended by the Forerunners.
