Azuran

Azuran is a fully oceanic Adeptus Astartes Homeworld that acts as the namesake for the Azuran Sector. It was first colonized by the nascent Conclave Ordinatum, a primarily Ordo Malleus conclave of Inquisitors seeking to find a safe and remote location to recreate the extreme success of the Exorcists chapter "Daemonic Possession Therapy" while bringing Imperial rule to a remote part of the relatively sparsely populated Segentum Pacificus in 980.M37 during the 23rd Sentinel Founding.

History
Azuran would not be the center of political influence and one of the two mightiest power bases in the remote Azuran Sector (alongside the Forge World of Ferunus) were it not for a group of Radical-Moderate Xanthite Inquisitors under the leadership of Inquisitor Lord Aeskos Naeron in the final decades of M37. Having long admired the efficacy and spiritual purity of the Exorcists chapter, the newly-formed Conclave sought to establish a base for it to recreate a chapter of Adeptus Astartes during the 23rd "Sentinel" founding under the pretense of securing a tattered border of the Imperium. In reality, they sought isolation and privacy. Making various modifications and improvements to the Exorcists' model, though lacking in resources, the Conclave was able to secure Exorcist trainers and equipment from various Segmentum Forge Worlds and prepared a group of 300 newly-gene forged Astartes - christened "Ordinators" by the Inquisitors - to be trained and led by Exorcists officers into the Eye of Terror where they, with the aid of their new Battle Barge and Exorcists escorts, managed to exterminate 6 Daemon Worlds with no instances of corruption, spiritual or physical.

With this success proving the worth of their experiment, the Conclave had a massive conical pyramid built on the ocean floor with state-of-the-art facilities for everything from training to gravitic plating to achieve Terran-norm gravity to hydroponic agriculture. The walls of the entire Fortress-Monastery were covered both inside and out with carefully laid down and highly powerful hexagrammic warding glyphs that would only allow warp entities to be manifested in a single, highly secure room at the base of the structure - now christened Arx Numinex. Underneath this, the Inquisition drilled nearly half a kilometer further and established a massive base of its own, exclusively for the Conclave Ordinatum - made up of the Ordos Malleus, Hereticus, Xenos, Astartes, and Sepulturum.

For nearly 5 millennia has Azuran stood, impregnable despite its frequent summoning of daemons for its "Rites of Purity" to cleanse the souls of its Ordinator inhabitants by forcing them to share a mind with a neverborn for hours before they are made to exorcise the daemon through sheer willpower or be executed. The chapter has made many enemies, however, and the thought that one day a reckoning might come to their beloved homeworld has sat uneasily in the mind of each Legate of the chapter since its inception.

Geography
Azuran is an entirely dihydrogen monoxide oceanic world with less than 2% of its surface area accounting for landmass in the form of isolated islands. Massive rainstorms rage across the world seasonally, making the few islands used by the chapter serfdom for agriculture, fishing, and even combat practice by the Ordinator Astartes available for only about half the year.
