25th Founding (40th Millennium)
The Celestial Guard are a Loyalist Space Marines Chapter created during the 25th Founding from the gene-seed of the Crimson Fists. Their Chapter homeworld is called Erenon and is a storm-shrouded Ocean World located to the galactic northwest of Nocturne.
- The Lycanthos Drift Campaign - Fourth Quadrant Rebellion (780.M41) - The Celestial Guard took part in the Imperial intervention in the closing stages of the long-running Fourth Quadrant Rebellion in 780.M41, undertaking a campaign against one of the last major stronghold systems of the revolt located to the galactic south of the Maelstrom Zone. During this conflict Lugft Huron, of the then-loyal Astral Claws Chapter, was elected as the overall commander of the joint strike force of a number of Space Marine contingents, compromised of the Celestial Guard, Astral Claws, Fire Hawks and White Scars, backed by Imperial Guard regiments from Krieg and Cal-Sec and the Titans of Legio Venator. Under Lugft Huron's inspired command, the task force ruthlessly purged the heavily fortified Lycanthos System of the Forces of Chaos in under a year.
- Siege of Erenon (997.M41) - The Celestial Guard defended their homeworld of Erenon from a siege by the Tyranid forces of Hive Fleet Leviathan.
The Celestial Guard's Chapter badge consists of two crossed axes. Comet decorations are often incorporated into their Power Armour.
