==Dreadnoughts==The '''Obsidian Glaives''' were an [[ImperialHomeworld]] of [[Obstiria]] is an irradiated world, which degrades the connections between the sarcophagus of a [[Space MarineDreadnought|Dreadnought]] and its pilot. These connections cannot be replicated by the Chapter and the degradation slowly poisons the Dreadnought's mind, causing them to constantly flashback to when they were still able bodied Space Marines, and eventually kills them. Because of this each of the Obsidian Glaives' Dreadnoughts are equipped with life readings, that display the amount of time each interned Space Marine has before death claims them. In order to expand that time for as long as possible, the Chapter keeps most of the Dreadnoughts asleep in a shielded vault, that protects them from the radiation, deep beneath the '''Penumbral Spike'''. Due to their adherence to the [[Codex Astartes]] , the Obsidian Glaives leave one Dreadnought active for a short time to serve as an honour guard for the [[ChapterFortress Monastery]]; before they are rotated with another Dreadnought within the vault. {{Fn|3b}} ==History==In 548.[[M41 ]] they participated in [[Helrac Incursion]] when piratical [[Eldar]] raiders used [[Space Hulk]] [[Mote of Darkness]] to bring war into [[Imperium]]. Thanks to [[Space Marine Captain|Captain]] [[Dynares]] of the 1st [[First Company ]] and [[Land Raider]] ‘Valour Maximal’ all the xenos on board of space hulk were destroyed.{{Fn|1}}
