Tips and Misc

Unlocking collars is a straight Strength check, or various Skill^† + d20 roll.

† Concentration, Disable Device, Repair, Open Lock, UMD, and "unskilled" (flat low percentage chance). (Slave Collar DC)

Start up the eastern side. You must reach the large room, aka the "lever room". (The western gate cannot be locked until after the end-fight room.)
(Optional) In the first side room, 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 hidden passage starts at the south end of the eastern hall. There are a half dozen bear traps and then 2 areas of (non-disarmable) fire jets. The passage leads north, first past a back door to the 1st side room (and the chest there), then further north up a ladder to the shrine room. The shrine room has a small drop-down, but there is no way back up.

Puzzle/lever Room:

A series of Spell Wards near the stairs make the direct approach more difficult. Swing counter-clockwise to avoid the first few, before going up the stairs.

There are 2 sets of 3 levers each, reading left-to-right we'll call these 1–3 (at the top of the stairs), and 4–6 (beyond the first gate). To simply proceed, and skip any optionals, you only need to pull 1, 5 and 6.

Pull Gate Control 1 lever at top of stairs

Lever 2, at the top of the stairs, should remain UP.
Lever 3, at the top of the stairs, does not matter for forward progress, it's only used to access the second extra prisoner cell.

Go down, through gate, and pull Gate Control 5 and Gate Control 6 levers
Path to exit should now to clear. These lever positions will keep the path clear:

UP: gate control levers 2,4
DOWN: gate control levers 1,5,6
(Optional) Lever 3, at the top of the stairs, only affects the side cell in the main room)
(Optional) Lever 4 DOWN opens the wizard's cell; be prepared to fight the hidden slaver (don't kill the wizard to get the optional). Make sure you put the lever again (leaving lever 4 UP) after the fight.

The levers labeled Cell Lever can be used to exit out of cells if you're trapped, and the one at the top of the stairs will open the first prisoner cell. Using them does not affect the above puzzle solution.

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.
Warning: Characters late to enter the first northern room will find a closed gate that seems to be barring their way, and there may appear to be no way to open this gate; simply clicking on the gate will move the characters into the next room. However, there is no direct way back (short of Dimension Door, etc.).
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.
After rescuing Ana, begin working south down the western half of the map.
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 may not be able to complete the optional if you haven't already freed 20 slaves.

Possible bug: killing the first group of slaves in the final fight too quickly (such as with an AoE insta-kill ability) may result in the boss never emerging from behind his magical barrier, and the quest becoming incompletable. Allowing enough time for the second set of slaves to emerge seems to avoid this problem.
