Talk to Irena and offer to find her daughter.

Go south to the Jail.

Right-click the Mercenary Captain, choose to watch, and observe his use of guards.

Talk to the Captain, ask if there's anything you can do for him, refuse to kill the Tenti's chief, and respond to his threats by stating he doesn't fight his own battles.

Kill the Captain to get a key. Use the key on the gate to enter the jail. (Do not equip weapons to avoid being thrown into a cell).

Talk to the slave in the green slave robe, agree to help remove his 'handcuffs', and trade your Desert robe for his slave robe.

Enter the gate at the corner of the mountain. Go to the far end, talk to the guard, and state you want to change your mining spot. He will ask for a pineapple.

Exit the jail and go west to the Tenti's camp. Talk to the head chief and request a pineapple. He will agree to give you one if you bring him weapon plans. Agree and he will give you a key.

Return to the mining camp, enter the surface building, and go up the ladder. Search the desk for a cell key. Talk to the occupant and yell 'Fire! Fire!'. While he's distracted, loot the chest. Return to the Tenti's camp and show the plans to the chief. He will ask for a bronze bar and 10 feathers. He will then grant you access to the tent across the small lake.

Show the plans to the guards outside the tent. Enter, use the bronze bar on the anvil to create 10 dart heads, and then use feathers on the dart heads to complete the darts.

Return to the chief and show him the weapon. He will give you a pineapple and the ability to smith your own darts, along with 6 bronze throwing darts. Go back to the jail, enter the underground, proceed to the far end, and give the pineapple to the guard. You can now enter the next part of the dungeon.

Move forward until you see a mining cart. Examine and pick up a barrel. Search the cart and ride it. In the next area, follow the middle narrow path to find Ana. Talk to her about escaping. Use the barrel on her to place her inside. Return to the mining cart, use the barrel to send Ana back, and then jump into the cart yourself. Search the barrels there to find the one containing Ana.

Go to the lift and use the barrel with it. Ask for help and answer the question with 'gregorious'. Return through the tunnels and exit the underground. Remember to wear your slave robe to avoid being caught by guards.

Jump on the cart and talk to the cart driver. Tell him some jokes until he laughs, then explain your situation. Ask him to drive the cart for 10 gold without questions. He will demand 100 gold; agree to his price. You will be back outside with the barrel containing Ana in your inventory. Head back to the gate and use the barrel with Ana's mother. Talk to her to receive your reward.
