The Carcharun are masters of the salt and surf, a species of shark-folk who have turned their predatory instincts toward the more complex games of trade, navigation, and regional politics. While their sandpaper skin and multiple rows of serrated teeth can be intimidating, they are just as likely to offer a fair bargain as they are to snap a limb, believing that a healthy marketplace is the most efficient ecosystem of all.

Carcharun are powerfully built humanoids with hydrodynamic frames and thick, denticle-covered skin that feels like coarse sandpaper. Their heads resemble various species of ocean sharks, featuring wide maws filled with revolving rows of teeth and jet-black or silvery eyes. They possess a series of sensory pores along their snout and flanks that allow them to detect minute electrical impulses. Most possess a large dorsal fin and smaller fins on their forearms, which they often pierce with gold or bone jewelry to denote their social standing.

Society is organized into 'Schools,' which function as merchant guilds and protective clans. In Carcharun culture, stillness is equated with death; this philosophy drives them to be constant travelers and ambitious entrepreneurs. They are highly pragmatic, valuing things that serve a clear purpose over sentimental trinkets. A Carcharun merchant like Kaimana Deep-Current views their shop as a territory to be managed with the same precision a hunter uses to patrol a reef. They are notoriously honest in contracts because they view a broken word as a scent of weakness that invites scavengers.

Most Carcharun follow a neutral philosophy, adhering to the laws of the sea and the balance of the hunt. They often worship the 'Ever-Flow,' a personification of oceanic currents and the inevitable cycle of the food chain. They tend toward Lawful Neutral, as they rely on strict maritime codes and trade laws to navigate the social waters of the surface world.

Their cities are marvels of basalt and reinforced coral, built into sea cliffs or submarine trenches. These dwellings are designed with 'current-flow' passages that allow water to circulate freely, though modern Carcharun enclaves in surface ports feature specialized 'damp-rooms' and saltwater pools to accommodate visitors while keeping the Carcharun comfortable.

They find elf-like species to be too flighty and dwarf-like folk to be refreshingly sturdy, if a bit too fond of dry holes in the ground. They are frequently employed as marine bodyguards, deep-sea salvagers, and harbor masters. They have a long-standing mutual respect with other coastal ancestries, though they remain wary of those who treat the ocean as a mere resource rather than a living sovereign.
