Bone Leech
The Bone Leech is a fairly small, worm-like parasite. A fairly weak creature, its power comes in its ability to infest and take over other creatures, providing it with a means of protection, a more effective way to attack, nourishment as it grows, and most importantly, a breeding ground for more Bone Leeches.
Soul Drudge
The Soul Drudge is a human who has been infested by the Bone Leech. It burrows into the chest of a normal human, and comes to rest on the upper spinal column of the infected person. From there it takes over the nervous system, circumventing the victim's brain for voluntary functions, but leaving the brain intact so that it will continue to handle involuntary functions. This allows the Bone Leech to control all movement of the victim, although it's control is difficult in the beginning, making the Soul Drudge a slow and clumsy creature. It makes up for this by being able to withstand a lot more damage than a normal human ever could, since as long as the Bone Leech is intact it can continue to manipulate the body. The Soul Drudge can lose limbs and still keep coming. It is believed that the victim is still completely aware, and can feel everything that happens to them, they just can't control their body. They can, however, control their speech. As a result, Soul Drudges often emit the wailing and torment of the infected victim. To minimize this the Soul Drudge sows its mouth shut and gouges out its eyes to make the victim more docile. The Soul Drudge will generally attack anything that gets too close to it, most likely out of self-defense, although packs of Soul Drudges have been seen hunting prey, presumably looking for hosts for more Bone Leeches.
The Soul Drudge is the first form the Bone Leech takes on. As it grows it evolves into the more powerful Drudge Lord, and finally, the Drudge Priest. The Drudge creatures are often seen working together, with the more advanced creatures ruling by cruelty and force. A pack of Soul Drudges will generally indicate that a more advanced Drudge creature is not far away.
