User blog:Arimik/Eternal Sons Chapter

The Eternal Sons chapter of Adeptus Astartes hails from the vaunted gene-seed of Robute Guilliman and is tasked with the protection of the Praxian Subsector. They are a fleet based chapter, the fortress monastary once rested upon the Imperial Captial world of Gravas IX but it was destroyed during a massive chaos legion invasion of that world. That invasion was shut down by the Eternal Sons along with support from the Adeptus Sororitas, but not without heavy losses to the chapter, the Adeptus Mechanicus now work to rebuild the monastary. That battle, coupled with a slight flaw in their gene-seed, one which causes battle-brothers to mature more slowly than normal and take longer to produce, means that the chapter is undermanned being able to only field around 700 battle-brothers in the most dire of situations.
