Garth Grimgar's Guide to the Flora of the Dying World

These are the field notes of the famously reclusive Occult Herbmaster Garth Grimgar, found in the ruins of his hut years after his death. The precise meaning of Grimgar's astrological diagrams was known only to himself. It is a secret he has taken with him to his grave. Despite the possibility that he was dabbling in blasphemy, the Church Elders have elected to preserve his notes for the potentially useful knowledge they might contain.
