Penance at Midnight

Penance at Midnight was the name of the Penance Crusade undertaken by the Midnight Claws Space Marine Chapter, following the unknown (and dire) events that transpired the previous millennium. In recompense, the Chapter volunteered to purge their self-perceived "sins" by undertaking a decades-long penance crusade, and bring the light of the Emperor to the darkest corners of the galaxy.

History
The Chapter would finally rebuild its number, achieving full-strength once again and beginning a penance crusade for their "sins" committed during the previous millennium. During this Crusade, the Midnight Claws encountered several chapters on their own crusades of penance. Together these Chapters formed in impromptu Conclave that would later venture into the heart of several long-lost worlds and bring them back into the fold of the Imperium, until their penance was over.
