Night of the Martyrs

The Night of Martyrs was a lamentable event in the history of the Invictors of Mars Space Marine Chapter, when the 9th Division (Company) was annihilated by the treacherous Night Lords Traitor Legion when they engaged in a brutal and bloody conflict upon an unknown world. There was only one survivor who managed to escape the slaughter, rescuing his Division's relics and precious gene-seed stores. Thanks to this lone survivor's efforts, the 9th Division would later be re-constituted, and the lone surviving sergeant was raised to the rank of Captain, and granted command over the newly re-constituted Division.

History
The 9th Division, while besieging a Night Lords fortress, were wiped out to a man, save one of their crash-landed ships bearing their precious relics and gene-seed. The ship's engines were taken down by the traitors for a more fruitful win and to gather more material for a faster production of Chaos Space Marines. After the battle was won, the 9th Division was to be rebuilt. The surviving sergeant was given the position of Captain to lead the newly reconstituted 9th Division.
