Diktamnon Herb

This herb was sought after by an old hermit above the estate of Dromeos. When encountered, the old man told the party that the herb could grant fish immortality.
They later learned from Dromeos that *Glaukos, the erstwhile ruler of the city of *Eidyla (toward which they were traveling) had apparently transformed into a fish and gained immortality.
Pyro later discovered and ate some of these herbs, finding them bitter.
