Space Sharks

The Carcharodons, also known as the Carcharodons Astra in High Gothic and sometimes as the "Space Sharks" in Low Gothic, is a Loyalist Space Marine Chapter of an unknown Founding, though it has been alleged to be either an ancient Chapter born as early as the Second Founding, or a relatively new Chapter raised during the 23rd Founding.

The Carcharodons is an alleged Successor Chapter of the Raven Guard, though this remains unconfirmed. They participated in the latter stages of the Badab War, returning from the outer void to punish those they saw as Traitors to the Imperium of Man and the Emperor.

The Carcharodons have always been a fleet-based Chapter, following the far rarer Nomad-Predation pattern rather than the more common Crusading pattern adopted by countless other mobile Space Marine Chapters.
