The Iriaebor Gambit

From the first page of the PDF:

There is turmoil in Iriaebor and some faction in the city wants to make sure that it continues unabated. Merchants are being slaughtered, their bodies displayed in the streets. Would the Dusk Talons be willing to go that far to keep their city free from the gauntleted grip of Elturel's Order of Torm? A Living Forgotten Realms adventure set in Elturgard for characters of the heroic tier (levels 1-10). (Note: This adventure is the second part of a trilogy. Playing ELTU4-1, ELTU4-2, and ELTU4-3 in order with the same character is recommended, but not required.)
