Deadbark Dryad

Deadbark Dryad
When a dryad fails to protect its wilderness home from a great evil and is unable to forgive itself, the dryad might transform into a wicked Fey monster called a deadbark dryad. Such dryads relinquish any compassion they once felt for living beings and instead harbor hatred for anyone who dares to invade their rotted demesne.
The wilds around a deadbark dryad become malignant, souring into a swampy morass of stinging nettles and noxious muck. Deadbark dryads are immune to this toxic bog's deleterious effects.
A deadbark dryad is typically bound to the spot where it failed to protect its charge. When a dryad transforms into a deadbark dryad, it becomes stronger and more violent, and it typically gains a renewed dedication to protecting its now-fetid domain. Most deadbark dryads would rather fight to the death than allow any intrusion into their homes.
Deadbark dryads are most often found on Krynn, but occasionally they are found on other worlds where magic and trees are plentiful.
