The Promenade

The Dryads appear to be nomadic in a way, traveling from distant places to reach these swamps. Most would not be able to tell them apart, but in watching them, I've noted the differences in their composition, and have traced their origins all across the island. This travel seems cyclical in nature, with a new group arriving every few months. Pliny the Elder wrote of elephants, reporting that they would ritually bathe each other to celebrate the new moon. Mayhap this rite is like that of the elephants, guided by a measure unknown to us? But what drives this slow Promenade toward Reekwater? Is it some form of pilgrimage? Or is there something else to it? I've attempted to find evidence that Dryads leave this place to travel elsewhere, and have yet to find any evidence of that. And as Reekwater is not overrun with Dryads in every nook, the only theory remaining is further proof of their level of intelligence: a knowledge of death, and a desire to do so in a designated place. But death holds almost no power here on Aeternum. What, then, is the purpose?
