Ana Brabener was captured by the Drow in the woods while she was searching for the Thread of the Weave. Go to the abandoned Temple of Mystra deep in the King's Forest and try to rescue Ana. Take the left fork out of Eveningstar, travel past a mill building with a rest shrine, and then go east through the swamp. Unlocking collars is a straight strength check, or skill + d20.

Eldrin Szind will run to each corner of the archive and cast two each of water elementals, air elementals, salamander firebrands, and steadfast armor. To avoid him sacrificing any prisoners it is best to enter via the hidden passage.

The puzzle has a toggling feature, in that one lever may open one door, but if the another lever is flipped, the previous one may open another door. This is do-able with a hire/pet. I did not write down my exact step-by-step, so I'll leave it for another trip through here or someone else who's better at describing puzzles.
 * The levers toggle the following doors:
 * The upper cell lever #a operate the first gate to the right #A.
 * The upper lever #1 operate the gate infront of the ramp #B.
 * The upper lever #2 opens the final door #G, though it also closes a door #D in between.
 * The upper lever #3 toggle the gate #F in between.
 * The lower lever #4 operate directly the gate #C next to it with the trapped war wizard.
 * The lower lever #5 operate the gate #D close to it, to open the passage modified by lever #2.
 * The lower lever #6 operate the final gate #E, to leave this room, as well as gate #B (see lever #1).
 * If you manage to get yourself trapped between doors, a sufficient jump skill may allow you to climb on the furthest cell lever and up to the wall. While you cannot go back into the main room this way, you can get back to the second set of three levers and free yourself.
 * From S1M0N5 on the forums: Lever 1 & 3 down then lever 5 & 6 down gets you through the gates to continue the quest. If you do lever 4 down before 5 & 6 you unlock the room with the War Wizard Orange name and his Slaver, kill the Slaver and release the Wizard then go back out and flip 4 again then 5 & 6 and you're through. As far as I can tell you can't get the other slaves without another party member or a hire.

Killing the nearby slaver (hidden until damaged or spotted) will cause the slaves to stop attacking. However, if another slaver enters range, they will become aggressive again.

Ana has a few options that allow you to control her motions. Basic commands are: "Follow", "Stay here", "Go Back". For the backtracking option, Ana will teleport back to the last rest shrine you have visited with her.

Defeating Phargred Avithoul (dungeon boss) will allow you to uncollar the villagers and purple knights that assist in the battle. While killing the villagers that are under duress will not hurt you (no hit to XP), you won't be able to complete the optional. {{XP bonus|n1=|n2=|n3=|k1=>52|k2=|k3=|t1=|t2=|t3=19|s1=|s2=2|s3=|b1=>37|b2=55|b3=}}
