Night hags create Tree Skinners by taking advantage of Dryads that have been driven mad by the death of their trees. The Hags promise the Dryads a chance to connect with trees again and induce them into submitting to a special ritual. The ritual used to transform a Dryad into a Skinner also installs in the Dryad a hatred of all Fey. The irony of a former Dryad using trees to murder Fey creatures delights the Hags to no end.
A feminine creature made of deacying, thorny plant life gives a wicked laugh as she touches a tree and disappears. Moments later, the tree emites the same laugh as it swings its branches.
