Izanagi (or Delta Aquilae g) is a human inner colony in the Delta Aquilae System, together with its satellite, the dwarf planet Izanami, with a more mountainous terrain than Earth and hosting a massive network of underground tunnels, some of which filled with liquid methane, dubbed "The Hollow". It was settled in 2454, with most early settlers being of Japanese origin, with Chinese, Korean and Indian people as major minorities. It has three continents; Amaterasu, Tsukuyomi and Susanoo, all of which are populated by scattered, minor settlements and lone homesteads. Aside from these, the planet has only one major city, Amenonuhoko, with a population of roughly two million.

Over the course of the Human-Covenant War, the UNSC assumed control of many parts of the Hollow, constructing a number of outposts within which they hoped would be able to survive Covenant glassing. One of these outposts was also turned into a detention facility for Unggoy prisoners due to its close proximity to methane. The Covenant eventually glassed both Izanagi and Izanami in 2544 - though Izanagi was only partially glassed, as the Covenant instead chose to build shipyards on the surface - after finding them due to a breach of the Cole Protocol committed during the Battle of Miridem. Though the UNSC outposts in the Hollow survived the actual glassing, the heat produced from the procedure converted portions of the liquid methane into gas form, causing any remaining humans to suffocate.

A new wave of human colonists determined to repopulate the colony discovered, however, that a considerable amount of the Unggoy prisoners had survived and proceeded to populate the Hollow, living their own lives. This discovery and the subsequent event was later named the "Izanagi Incident", as the discovery caused the Empire of Cerbus to raid and sack Izanagi, killing the human colonists and taking away most of the free Unggoy in the hope of replenishing their failing army. The incident caused an outrage amongst the human population, some demanding a declaration of war against the Empire of Cerbus (despite the UNSC military's weak state), while others requested a removal of the remaining Unggoy - who was blamed for the incident by many, as it had been because of them that the Empire of Cerbus had risked the attack. Ultimately, the UNSC chose to simply abandon the planet and its satellite and declare it off-limits for future colonization efforts until further notice.

Behind the Scenes

  • Many names for the planet's locations and fellow stellar objects were taken out of Japanese Mythology, the most notable being 'Izanagi' itself, which was taken from a deity figure of aforementioned mythology, who was the husband and father of four other deities, namely 'Izanami', and 'Amaterasu', 'Tsukuyomi' and 'Susanoo', respectively.
  • "The Hollow" term was borrowed from Gears of War, where "The Hollow" is the name of the network of tunnels inhabited by the Locust Horde.
