Daroth

Mentioned as "collecting a sample" from a Dreg-Feredir in the Thanedell Expedition Journal, Daroth was the first Sylvan that Skreeek met after reaching the mainland. Daroth was very friendly, and got Skreek a bit drunk that evening as they traded stories.
Weeks later Skreek realized that his birth-shell was missing, and didn't figure out that Daroth had stolen it until reading about it in the Expedition Journal.
