Lore:Revolting Life Cycle of the Dreugh
Contrary to local myths about the origins of this base species, the dreugh migrate from the Abecean Sea into the lakes and inlets that feed into the Iliac Bay. In addition to their mass of clawlike limbs, pincers, and scuttling feet protruding from a human-torso-sized skeletal frame, the dreugh wear armored hides and secrete shell wax that are prized in some quarters. They are aquatic scavengers, spending much of their time in deep ocean water. Local fishermen tell of altercations with this species (such as when the dreugh cut fishermen's nets to steal fish), but dreugh are mostly mild-mannered, except during karvinasim, their period of transformation.
During karvinasim, dreugh walk upon the land, favoring shoreline marshes and rivers close to the open water. Hatchlings are closely guarded, and broodmothers are extremely territorial, reacting to invaders with both speed and hostility. This leads credence to the notion that karvinasim heightens the dreugh's martial instincts: Indeed, after witnessing the evisceration of our lead geographer Pulcherius Pomptinus, our raiding party thought twice before capturing and culling further specimens.
After a year of land walking, the dreugh return to the water. As they submerge, they undergo a final transformation known as "meff," where they devour their land skin and air organs—the body parts they no longer need—and then vomit the congealed remains as small fibrous balls that are approximately a foot in diameter. These disgusting and foul-smelling spheres are known as "grom" and are found in clusters around lakes. So far, our apothecaries have discovered no virtues in grom, aside from inducing queasiness in some of the more weak-stomached members of this contingent.
