From the Introduction: The Crypts of Kelemvor is a one-shot adventure for characters of levels 3 to 5, adapted from a quest in Neverwinter online. This scenario sees the adventuring party given an important quest to collect a number of broken magical seals and to light a number of magical braziers, all of which once protected the crypts of Kelemvor. In so doing, they can help to quell a devastating uprising of undead—organized by a powerful lich named Idris bent on destroying the city of Neverwinter.
