Substance, also referred to as Coelest IV,[4] is a blue-white ice giant in the Coelest system.[2][1] It is the fourth planet in the system and is the planet which Installation 05 orbits.[1][2] Substance is orbited by eight satellites, only one of which, Opusculus, is a natural moon. The rest include Installation 05, and six dormant Forerunner facilities on predetermined orbital paths.[2][1] An asteroid field is located close to Substance at 2.4 AU from Coelest.[5] Unlike on Installation 04, where its parent planet Threshold could be seen quite clearly, especially at night[6] on Installation 05, Substance is very difficult to see in the sky of Installation 05; this is due to the Delta Halo's stormy weather conditions caused by a Flood outbreak that occurred some two centuries before the Battle of Installation 05.[1]
History[edit]
Human-Covenant War[edit]
During the Great Schism that began on Installation 05, Sangheili and Jiralhanae vessels battled each other over Substance.[7]
Weeks after the battle and the subsequent Fall of High Charity, the UNSC Coral Sea picked up a dying San'Shyuum aboard a skiff drifting in a debris field irregularly orbiting Substance.[4]
Production notes[edit]
While not named during Halo 2, the file containing the planet's graphics were found to be named "Substance". Similarly, there was a file called "Threshold and Basis" in Halo: Combat Evolved.[8] The planet was first officially identified in Halo: The Essential Visual Guide.[1]
The Halo Encyclopedia (2009 edition) incorrectly states that Installation 04 orbits Substance. This error was not corrected in the 2011 edition.[9]
