and stall partly into the process Other genetic errors can occur, and sometimes disease or heredity affects the change for the worse These malformed hybrids rarely gain a formal position within the deep one society but instead tend to be hangerson The deep ones or more fortunate hybrids sometimes use them as tools or pawns Under the Sea Deep ones are generally one of the most socially and magically sophisticated races of the sea, in their own unsettling way They typically construct large and complex cities deep under the waves When these are located near a shore, the local population is often subverted by the deep ones in many ways Deep one society is stratified and controlled by its older, higher ranking members One feature of deep one biology is that, if fed sufficiently, they continue to grow to indefinite size Their leaders ensure that this only proceeds under their control: only those deep ones that are needed to be huge in size are permitted to grow unhindered On occasion, there have been entire cities of gigantic deep ones, but in a typical city, only a few individuals exceed the normal size because a large population of huge deep ones requires more food than most cities can support Also, giant deep ones cannot breed easily with the mortal races When deep ones grow to Large size, they not necessarily stay humanoid in appearance Their body form can continue to mutate and adapt, and so extremely large individuals may look very different from their smaller kin 196
