Carcharodons - Chapter Homeworld: The fragmentary records of the Carcharodons indicate that the Chapter has no set homeworld. This is not uncommon for Space Marine Chapters; the renowned Black Templars Chapter, for example, operates solely from its substantial warfleet as part of a perpetual Imperial Crusade. However, the Carcharodons do not appear to follow the Crusade Chapter pattern of operations, relying instead on a much rarer operational strategy known as the "Nomad-Predation" pattern.The Nomad-Predation pattern evolved in use by Space Marine Chapters and certain Rogue Trader fleets operating beyond the Imperium's boundaries for extended periods of time. It refers to an entirely self-contained force that can sustain itself without any Imperial support whatsoever.A Nomad-Predation fleet may contain as many support vessels as true warships, or it may contain voidships capable of both combat and maintenance repairs. This second possibility may be more likely in the case of the Carcharodons; given the bellicose Chapter's propensity for combat, it seems unlikely they would tolerate vessels in their fleet's ranks that could not hold their own on the battle line.A Nomad-Predation fleet voyages endlessly, pausing only to identify and engage its foes. It must choose its targets carefully, selecting those within its means to destroy without threatening the fleet's viability as a fighting force.Once it selects the appropriate victims, it can descend upon them quickly and savagely, engaging and destroying potential threats or launching spoiling attacks against foes too large to attack in force. The fleet obtains resources from the vanquished foe before vanishing, safe from any potential retaliation.Though one cannot be certain that this is the means by which the Carcharodons operate, the tactics do seem to perfectly fit their observed behaviour. If this is the case, the Carcharodons most likely replenish their ranks in the same manner as other Chapters that follow the Nomad-Predation pattern. Namely, they cull potential Initiates from amongst the young of the survivors of their assaults, provided those survivors are human and free of the corrupting influence of the Warp.This culling for potential aspirants is known amongst the Carcharodons as a "Red Tithe." These Initiates must be subjected to intensive hypno-conditioning and other harsh procedures designed to strip away any past loyalty, replacing it with the will and attitudes of the Carcharodons.If they successfully passed their induction trials, initial surgery and indoctrination, these Initiates become Scout Marines. When not training with their fellow Scouts in the 10th Company, often times they will be attached to one of the Chapter's nine Battle Company commands, in order to gain combat experience.After being bloodied in battle over the course of a solar decade or more, they will begin to earn their first Exile Markings, jagged tattoos that often spiral in loops up their bared forearms and across their pale, shaved scalps.When they are on the cusp of becoming full members of the Chapter, they will eventually leave behind the number designations all Scouts are known by in favour of a true "void name," swapping their grey carapace plates and black multiweave fatigues for the coveted Power Armour of a full Void Brother (Battle-Brother).
