Enter the palace district and turn right, where you can see the imprisoned Ogre. Make your way through the area, killing dwarven soldiers and avoiding the ballista along the way, and head left and up the stairs. Kill Kardol on your way up. At the top of the stairs you will battle several dwarven soldiers and Steel Golems.
Once the area has been cleared, pull the two levers (one on each side) to raise the portcullis and release the Blight Wolf and the Ogre. Enthrall both of them.
Before smashing the nearby gate at the bottom of the stairs, use the Ogre to smash the barricade to the left of the stairs (this area will be marked as Side Alley on your map). Inside you will find Sergeant Kylon, a Knight, and some innocents. Loot the chest for Ring of the Warrior, and Kylon's corpse for Deadhead Charge. Then use the ogre to smash the gate at the bottom of the stairs to open the way to Fort Drakon.

- Gift found on Kardol.
The area has several places in which enemies will infinitely re-spawn. This means you can easily get the Enthralling achievement, but note that the re-spawns can sometimes "dry up", such as the spawn point in the palace. It can be reactivated by commanding all characters to hold position at the palace's front gates and walking down the stairs that lead to it and then back up.
