I've heard that there's an ancient grove sacred to Jhebbal Sag somewhere in this forest, said Conan. I don't know. I've never seen it. But more beasts remember in this country than any I've ever seen.> - Beyond the Black River
The groves of Jhebbal Sag are said to be the places where the god walks when he chooses to visit this world. In the shamanic traditions of the Black Kingdom, the groves of Jhebbal Sag are spiritual places, reached only through meditation and the ingestion of certain mushrooms.
In the Pictish Wilderness, however, it is claimed that such a grove exists in the physical world.
Perhaps they are both one and the same place, and it is the astral voyaging of shamans that brings them face to face with the awesome power of Jhebbal Sag.
This flower, gathered in a place that may or may not have been a dream, can facilitate the power of Jhebbal Sag in beasts - increasing the chance of them growing larger and stronger.
