The Shadow of Meresis.

This mod adds an extensive quest leading to various locations throughout Skyrim. In addition to new areas and dungeons, you'll encounter new NPCs with over 200 fully voiced lines of dialogue spoken by three actors. The game time is about two to three hours. You will find a corpse on the banks of the Kart River. The man died without any visible signs of physical injury. On the man's neck you will recognize a shiny black amulet. You take it without hesitation. You wake up to find yourself sweating in the Four Shields Tavern in Dragon Bridge. A young servant of Stendarr is watching you. Closing your eyes, you hear it again in the distance: painful voices and dark shadows, chasing you in a feverish delirium. The quest starts at the Solitude Lumber Mill (south of Katla Farm).
