Eeknot

While an Eeknot is not one specific creature, it is a collection of symptoms that one may come across in their travels. There are many monsters that either rape, or inject their eggs into a human host so that their offspring can feed on the host. This is normally a death sentence for the host, but after about a month the host usually goes violently insane and starts attacking even their own family members. Eeknot is a old Fawl term for a person savagely insane due to a parasitic embryo. Eeknots are usually murdered so that the monster can never actually develop. Otherwise they rush into either a body of water or forest killing anything in their way,  so that the offspring can rip through their flesh peacefully.
