Hexodivus

Hexodivus is a notable Imperial feral world and Adeptus Astartes Homeworld of the 'Cursed' Founding Midnight Claws Space Marine Chapter. The early history of this isolated world is relatively unknown in official Imperial records, however, it is believed that the Midnight Claws laid claim to this world, by right of conquest, sometime in late M35 or early M36, not long after their inception.

Background
The Adeptus Astartes Homeworld of the Midnight Claws Chapter is the planet Hexodivus, a world engulfed by perpetual night and is made up of large plains and mountains. The Midnight Claws' homeworld suffered major damage to it's wildlife and several continents due to the earlier Ork invasion. The Chapter had to intervene to prevent an extinction event, having to remain in a defensive state for a few hundred years.

Fortress-Monastery
The Midnight Claws' fortress-monastery was named by the Chapter as the ' Shadowed Bastion ' - a huge castle that stood in the center of their homeworld's second largest continent. Spires were seen seemingly growing from the ground and stretching high into the atmosphere, filled with artillery platforms at each level. A security tower was placed at the top, where shifts of heavily armed servitors watched over the darkened lands surrounding the mighty citadel. During the attack of the invading Ork WAAAGH!, regrettably, the fortress-monastery was destroyed when a gargantuan squig rammed it several times at a critical point of the citadel's foundations, bringing it crashing down. The Shadowed Bastion was later rebuilt, gaining a defensive wall with jagged fangs as a countermeasure for anyone who attempted to climb it. As of now, the fortress-monastery still bears all the genetic material and relics the chapter possesses. Inside, the Reclusium, Librarium, Apothecarion and Technorium are located deep within.
