Holdfast vine

Holdfast vines were a peculiar breed of vine blights that had apparently not been spawned from a Gulthias tree. They were found in Forestfall Fen as of the late 15 century DR.

Behavior
Holdfast vines had a thirst for fresh blood, and would seek it out by attacking anything that moved. They would lie dormant in the swamp until fresh blood revived them, and if slain, their forms would be consumed back into the swamp to feed it, a process which also alerted nearby holdfast vines of danger.

Ecology
The holdfast vines appeared to be a defense mechanism spawned by the gloomy Forestfall Fen, which proved to be a suitable environment for these vine blights despite the lack of a Gulthias tree. Holdfast vines appeared to be connected to trees which had become hale and hearty on a diet of blood.

History
In the late 15 century DR, ongoing conflicts between the Queenstooth kobolds and Muckgrunter trolls in Forestfall Fen took a bloody turn with the advent of an invasion of meenlocks from the Feywild. As the Fen's baseline level of conflict was suddenly escalated into a much bigger fight, more blood began to be spilled and soon the holdfast vines awoke to wreck havoc on all sides.
