The appearance of the shades at Burgûl-stazg disturbed the Elf Mothelen, foreshadowing a more dire evil.
'${PLAYER}, I fear something dire is about to occur. The shadow of the Necromancer lies still upon Mirkwood. I know little more of these forsaken shades, but perhaps you may learn more if you speak with Prestadír at the Haunted Inn.
'The Haunted Inn lies to the east of here, deeper into the Dourstocks.'
Prestadír is at the Haunted Inn, east from Echad Mothelen.
Mothelen suggested you speak with Prestadír to learn more about the shades of the Dourstocks.
