Following the creation of the Crimson Sentinels Space Marine Chapter during the Second Founding, following the sundering the Space Marine Legions into smaller, sperate Chapters in 001.M32. Since that bygone era, this formidable vessel has honourably served the Crimson Sentinels during countless campaigns down the long millennia.

History
An Ancient Legionary Blood Angels Battle Barge thought to be lost to the warp during the Horus Heresy. How ever the massive Battle Barge was found around orbit of Dermanus, its hull flooded with the noxious gasses of the gas giant's form. During the Armada Rebellion, the hulking vessel was found by Armada loyalists and attempted to salvage the craft for their own gains. What they did not expect how ever were Blood Angel Dreadnoughts from the Heresy in suspended animation for thousands of years, they were awoken from the automated security systems going offline.

A group of three Castraferrum Pattern and two Contemptor Pattern Dreadnoughts were able to remove the Armada loyalist from the ship and aid Crimson Sentinel Shield-Brothers in removing the rebels from their rightful claim. After much discussion with the lead Contemptor Dreadnought of the group, Venorus, by Tiberius Demokan. The Dreadnoughts and the ancient Battle Barge were allowed to join the Crimson Sentinels as a sign of gratitude and respect for defending the might vessel and overseeing its repairs to space voyage.

As of M42, the Spear of Sanguinus is seen as the Crimson Sentinels' flagship to this day. Charging head first into enemy lines and blasting them apart just as the might Primach Sanguinus did himself.
