These strange aberrations are less than 1/2'' across and group up in hives of up to 5,000. They inhabit corpses and weave countless strands of high tensile strength webbing into the muscles, bones, and joints. They lay a large and heavy sack of eggs in or around the "gut" area of the being. They are able to construct a system of "levers and pulleys" with the limbs and are able to animate the corpse. They control the limbs with thousands of tiny beings pulling in unison to achieve movement. They are natural necromancers, and they use the host body's own memories as instructions for how to use the particular body. As they hive inhabits the body longer, they become better and better at using it, until they are nearly superhuman.
