The Mere of Dead Men

The Mere of Dead Men (or Merdelain, meaning "Slow Marching Court" in Elvish) is a swampy area located along the Sword Coast North. The party passed through on their way to Baldur's Gate from Philander, and were ambushed repeatedly by flying Kobolds, Lizardfolk, giant Frogs, and other creatures. Sirius and Ascot were slain in one such ambush, and their bodies vanished when Elerra cut a deal with the Talking Raven.
