Caspian Artorius

Caspian Artorius was the first Lord Commander (Chapter Master) of the Imperial Sentinels Space Marine Chapter, a notable 3rd Founding, fleet-based Crusading Successor Chapter descended from the proud and stoic lineage of the First Founding Imperial Fists.

Background
The first Chapter Master of the Imperial Sentinels was the Imperial Fists Company Captain and former Praetor Caspian Artorius, a keen naval strategist and adept swordsman. These traits marked him apart from his fellows, and when the Primarch Rogal Dorn set into motion the 3rd Founding in 001.M32. Caspian was selected to become Lord Commander of one of these new chapters. Tasked with taking to the stars to continue the scouring, to bring the wrath of the Emperor and His grieving son to those deemed responsible wherever they attempted to go. A mandate the newly dubbed Imperial Sentinels and their chapter master would earnestly obey. As is custom for a Founding the Sentinels were armored, armed, and equipped as befitted true sons of Dorn with a massive flagship Battle Barge, dozens of suits of Tactical-dreadnought armor, 1,000 gene-seed samples, hundreds of armored vehicles and aircraft, and more. For no expense is spared when it comes to His Angels of Death.

For a century the chapter built itself up, training, fighting alongside their Primogenitor Chapter till they were individually combat effective. Then they were unleashed. The first to be ground to dust by the Imperials Sentinels were a roving band of Word Bearers Heretic Astartes, whose name has been lost to history, that had been assailing the frontier Forge World of Actium. The pitiful Traitor fleet was torn apart by the Blade of Retribution, with Caspian at the helm. From the heavens rained bombardment cannon shells and lesser ordnance issued by the chapter’s strike craft, but these were little threat in comparison to the Sentinels themselves. Through the fires set aflame by the conflict strode the ebony armored Terminators of the 1st and 2nd Companies, the Templar Brethren. Behind them in lockstep marched the Sternguard, Vanguard, Tactical, Assault, and Devastator Marines with Caspian at their head. This precedent for leading from the front set by the first Lord Commander would carry from the War of the Beast, to the Age of Apostasy, and beyond. Suffice it to say the Word Bearers did not survive, their corpses burnt after being relieved of their most valuable pieces of wargear for reconsecration and reuse in the Emperor’s name.

Then as quick as they came the Sentinels set sail, after repairs and the collection of possible aspirants from the ravaged world’s population that is, towards the next war zone. As would become customary for them they refused a formal thanks and/or celebration, taking their recompense in repairs, resupply, and equipment.

Wargear

Many a Chaos Lord, Ork Warboss, Aeldari Exarch, Druhkari Archon, Tau Commander, and Tyranid Hive Tyrant have been laid low by the razor sharp edge of Bitter Valour as well as untold millions of lesser foes since the first Lord Commander took up this sword.
