Apparently she sought a way to defend the coven in case of attack, and created the Thorns. She watered thorny bushes with her blood, and collected their seeds on a Thursday night in a small box covered with runes. Inside the stomach they quickly start to grow, sending out thorny tendrils through the body, reaching into the heart, muscles and brain and piercing the skin with black thorns. Needless to say the agony is beyond words. Wounds are closed as thorns sew them together, muscles are strengthened by resilent wood.
Some users can even attack their enemies with their thorns.
A group of thorn warriors is a horrible threat for almost any enemy. As the effect wears down, the thorns start to die and the body is magickally healed. Unfortunately the healing is slow, as most of the resources of the body have been depleted and the wooden parts only dissolve slowly. This is not a rote to use lightly. It has happened that the user has been killed despite the thorns and their healing powers.
