Changeling Parasites

While stationary, The changelings inches-long humanoid torso can be seen with dozens of small limbs sprouting from shoulders, legs and neck.

Changeling parasites take control of a host by digging their limbs into the host's nervous system, eventually working their way entirely under the skin of the subject. The parasites will only attempt this if the fruit is eaten or if they are forcibly removed from the fruit or their current host. A parasite will seek the nearest controllable being it can detect.

While other fey are not immune to the changeling parasite's control, they have a chance to regain control over their bodies and remain conscious through the ordeal. Midwives are immune to the parasite's control due to the cold iron used in their construction.

Ingestion of water infused with rowan-wood will kill the parasite inside a body.
