40K Lore: The Space Sharks


Today Loremasters we discuss a chapter at loyal as they are bloodthirsty – the Carcharodons (low gothic: Space Sharks)

The Carcharodons (also known as Space Sharks or Carcharodon Astra) are a loyalist Space Marine Chapter with a reputation for ruthlessness and brutality.


The Chapter named Carcharodon Astra —translated into Low Gothic as the Space Sharks, but known more widely as the Carcharodons – is a Space Marine Chapter of unknown provenance that has relatively recently carved for itself a dark and brutal legend in the bloody wake of the Badab War. Much of the information surrounding its history is shrouded in myth or allegory, but fragmented pieces of data point to it already being in existence as early as late M32, during the Astropath Wars. One thing is for certain, however: that the Chapter was given a sacred duty to travel the empty spaces beyond the Imperium‘s borders, seemingly forever, to seek out and destroy the enemies of Mankind.


The Badab War

The Carcharodons’ entry into the Badab War was as sudden as it was unexpected. The Chapter’s fleet, led by the battle barge Nicor and composed of a mix of medium and light warships, arrived without warning at the edge of the Golgothan Wastes, and was initially met with alarm by Loyalist and Secessionist alike. After a quick conference with the leaders of the Loyalists, however, the Chapter’s alignment became clear, and the Carcharodons were warily accepted into forces of the Imperium.

The Chapter quickly established a bloody reputation for itself as it engaged in a campaign of systematic annihilation of the worlds of the Endymion Cluster, whose inhabitants still owed some loyalty to the Mantis Warriors. Planet after planet was placed under a scorched world policy, their infrastructure smashed and countless multitudes slain, which forced the hand of the Mantis Warriors, whose honour would not allow them to stand by and see people suffer. This played into the plans of the Carcharodons quite nicely, and soon all resistance from the Mantis Warriors was crushed, their days as an effective fighting force over.

Unable to deny their effectiveness despite his own misgivings, Commander Carab Culln gave the Carcharodons the responsibility of attacking the primary infrastructure of Badab Primaris, while the Star Phantoms prosecuted the attack on Lufgt Huron‘s seat of power. The Chapter interpreted the orders in their usual brutally efficient manner, and sabotaged the reactor cores of the primary hives located on the planet. The resultant tectonic upheaval broke the back of the Secessionist forces, but also kick-started the process of the world’s demise. Countless Loyalists died in the hurried retreat that followed, and to this day it is said that the Star Phantoms hold the Chapter in ire for what happened.


War’s End

With the reign of the Tyrant of Badab at its end, the Carcharodons would return one final time to the Endymion Cluster, and aided the Fire Angels in bringing back the worlds there into compliance. With the blessings of the Fire Angels, whose dominion over the Cluster had been granted at the cessation of hostilities, the Chapter visited the Tranquility system. There their dark legend would be sealed. The hidden fortresses of the Mantis Warriors were ransacked of supplies and war materiel, and a whole generation of the system’s young men were taken away to replace the losses the Chapter had incurred during the war, forced to fight each other to the death to see who would be worthy to join the Carcharodons’ ranks.

With that the Carcharodon fleet disappeared, apparently returning to the dark void above the galactic plane.

Organization & Tactics

The Carcharodons roughly follow the organizational tenets laid down in the Codex Astartes, but otherwise show considerable variation with regards to tactics. In particular, their preference for shock assaults and close combat make them similar to the Black Templars, at least in the eyes of the Fire Angels Marines that accompanied them during the length of the Badab campaign. The forces observed during the war show that, on the surface, the Carcharodons were deployed similarly to what might be expected of a Codex Battle Company, although it was noted that it was augmented by an auxiliary force of Scouts and dedicated squads of Terminator-armored Veterans.

Although the Chapter seemed to maintain a sizable amount of armoured vehicles, the Carcharodons as a whole seemed to prefer infantry-based strategies, relying on the battle-prowess of its Marines to carry the day. Lightning assaults presaged by reconnaissance by small scouting forces was commonly observed, with surprise often the key factor in carrying the attack through. When resistance proves too heavy or the reaction of the enemy too swift, the Chapter’s forces often quickly withdraw, to avoid heavy losses and, more importantly, to strike at another direction. This is repeated again and again until a weakness is eventually found, upon which the full brunt of the assault forces are brought to bear to bring the encounter to a swift end.

The Chapter’s armory was noted to consist mostly of old-style suits of Power Armor, particularly the Mark-V Heresy Pattern, and weaponry. The Carcharodons’ complement of Terminator Armour in particular showed extensive modification to keep them combat worthy.

~Fighting the Carcharodons is like this… but in space.

  • SilentPony

    You…you really don’t read the comments at all do you?
    We went over this days ago.

  • Fortnight

    These guys are the loyal remnants of the terrans, Corax “banished”, or at least some of the loyal remnants. There may be other factions as well, and there are at least one group that went blackshield and stomped/absorbed the Night Lords remaining in the Nostramo Sector during the scouring.

  • Painjunky

    The sabotaging of nuclear reactors, establishing a bloody reputation, lightning assaults, ransacking, theft, scorched world policy, overt violence, shock CC assaults and enslaving generations and forcing them to fight to the death reeks of night lords… tho probably not exclusively.

    • Fortnight

      These are Raven Guard. They are the Terran originals that operated under Horus during the crusade. Corax sent them on a never ending crusade or “Nomad Predation Fleet,” effectively banishing them. They were just too brutal for a Primarch who cared a so much about people. There are other factions from the predation fleets that still survive. The Ashen Claws for example tuned their back on the Emperor and Horus as well, they are rumored to still have a pocket empire in the Ghoul Stars. All the OG 19th descendants though are pretty brutal and operate a bit between the Luna Wolves and Night Lords, in attitude.

      • Bulvi Nightbane

        Correct, they are Raven Guard descendants who use a combo of Raven Guard and Luna Wolves tactics. The brutality comes from originally fighting alongside the very brutal Luna Wolves recruits from Cthonia.
