Deep within the Neverwinter Wood, the embers of an ancient empire rekindle. Conspiracies lie behind every tree, and shadows blur the distinction between friend and foe. Caught between vying powers, a woman stands trial for the murder of her friends. A Living Forgotten Realms adventure set in Neverwinter for characters of the Heroic tier (levels 1-10).
This adventure is the second part of the Devil's Play Major Quest. This series of adventures (which begins with NEVE5-1 and concludes with NEVE5-3) is best experienced in order.
