Black Anemone

This unusual plant grows in the rocky and windy walls of Pandesmos in Pandemonium. It usually grows under the surface and it digs most of its body, not only the roots, into the solid rock. Its roots exude a corrosive substance that gradually melts the stone turning it into nutrients that feed the plant. Once every several cycles (different surveys say a different amount of time) it blooms only one great black and beautiful flower. Its petals can be ground to brew a powerful pain increaser. Anyone who drank the liquid would have his pain sense multiplied and any sensation that led to a pain would become the most distressing situation that he'd ever lived. Many people become barmy with the use of this brew very valued to torturers.
