Dereliction of Duty

Dereliction of Duty is a quest received from The Blackstone Irregulars Quest Board.

Background
Several members of the Irregulars have gone rogue, and grabbed a little five-finger discount along the way. Track them down and explain how the Irregulars feel about this.

Walkthrough
When you find one of the members, a dialogue will start where you have two options. Whichever one you select does not matter, they will attack you regardless. After you kill them, be sure and loot their body and pick up the "Guild Supplies" (otherwise the quest won't finish). There are three members to track down; the locations are as follows: Return to any Blackstone representative for reward.
 * Frostback Mountains - standing to the right of the large stone circle before the entrance to Orzammar.
 * Lake Calenhad Docks - standing in front of the Spoiled Princess Inn.
 * Denerim City Map - hangs around inside the "Dirty Hovel" of one of the rundown, criminal districts (fix me).
