A Shadow Falls

A Shadow Falls is the name of the lamentable period in the annals of the history of the Storm Sentinels Space Marine Chapter, when the cancer of Chaos had secretly began to take root within the ranks of the Chapter and spread over several decades.

Background
During the recruitment of new Aspirants on Ignis VIII, Captain Solaris challenged Chapter Master Remus in the Chapter’s Annual Battle for Ascension in which a member of the Chapter challenges the Chapter Master for his rank. Solaris and Remus fought against each other in a gruesome match, both trading blows until Remus was knocked down by Solaris, who then raised his weapon, and slew Remus. The audience was shocked to see a Captain beat the Chapter Master, and to see one of their greatest Chapter Master’s corpse lying on the ground. Solaris was sent to the Chapter Chaplain for reconditioning and a mental examination.

Solaris revealed himself to the Chaplain, as someone who the Chaos God Khorne blessed with almost unrivalled power. He then slew the Chaplain, and had begun his rule over the Chapter. He led the Chapter in constant Xeno purges within the Segmentum Tempestus, within 10 years, he was able to colonize 4 planets which were heavily defended by xenos species.

During this campaign, the Chief Librarian called Inquisitor Mortaic Durm to investigate the Chapter Chaplain’s disappearance. Durn traced the Chaplain’s death to Chapter Master Lysander Solaris, and all his previous crimes, including the murder of Captain Noctis Antellis, and it was discovered 5 puncture wounds were from a stab of Cataphractii Lightning Claws. It was suspected that Solaris had fallen to worship of Khorne, it is possible this affected his leadership skills and strategic ability, causing heavy casualties upon his Company and Chapter. The reports during the war against WAAAGH! Skullboila could be true that Solaris died, however Khorne may have resurrected him for some unknown reason.
