The quests consists of two parts: (A) place a message in a hollow log and (B) speak to Alari Doubleblade. The shortest path to the hollow log starts from either The Wilds or Druid's Overlook heading west into the Mamnoon Lagoon; the log is not far from the portal. To reach Doubleblade, either continue west or map to Quarrel Falls to get to Silverwood; once there, your contact is a couple minutes walk.
