The Tourist Trap

Getting started
Talk to Irena just outside the Shantay Pass. Ask her about her daughter until you offer to find her. After starting, unequip all of your metal armour, and put on your desert robes. Since you're in the hot part of the desert, your character will grow thirsty and take a drink of water as time passes. Desert robes will make your water last longer, and you can refill your waterskins by cutting cacti found around the desert with a knife or a slash weapon. From the Shantay Pass, go south to find some footprints. Follow them until you reach some Mercenaries guarding the gate to the Desert Mining Camp. Search the gate and use the "watch" option on the captain, then talk to him. Compliment him and agree to do him favours until he asks you to kill an infamous bandit leader. Accept. Head directly west until you reach the Bedabin Camp. Inside the large tent, you will find Al Shabim. Ask him about the bandit you're looking for, and he will tell you the bandit doesn't exist and send you back to talk to the Mercenary Captain again.

The Fight!
Tell the Captain that there is no bandit and insult him for not knowing as much to get him to attack you. Kill him and take his key.
 * Note: Unequip everything except your desert robes before going through the gate!

Getting into the mine
Unequip all armour and weaponry after defeating the captain, and before entering the camp. Inside the mining camp, wear only your desert robes. Once inside the camp, go into the building to the north, and search the table with a bowl on it. You will receive a Cell door key, which will save you time if you get caught in the upcoming sections; simply use the key on the jail door if this happens. You also can refill your waterskin from the bowl. Now, run to the east wall, and talk to a slave. He will tell you that he's planning on making an escape. Tell him that it sounds interesting. Help him remove his handcuffs and switch his Slave robes for your Desert robes.
 * Warning: Once you have entered the underground mine area, do not remove your clothes around the guards or mention the key, or you will be jailed and forced to mine 15 rocks to be freed, to be handed in all at once. You will lose anything you dropped to make space. Teleporting out is possible.

Wearing the slave robes, enter the mine and follow the path until you come to a guarded door. Talk to a guard and tell him you want to mine in a new area, and he will request a 'Tenti' pineapple. Remove your slave robes to be sent to the jail. Then, escape jail by using the jail key on the cell and leave the camp. If you do not have the key, you can escape jail by bending the cell window, climbing out, climbing the rocks and cliff, and descending outside the camp.

Go back to the Bedabin Camp and talk to Al Shabim. He will agree to give you the pineapple if you get some weapon plans for him, and gives you a key.

The plans
Go back to the mercenary camp and enter the prison. Climb up to the ladder to where the captain is and search the southwest bookcase to learn he has an interest in sailing. Try to open the chest and he will notice you, and you'll be given a number of options on how to distract him. This will get him distracted enough for you to search the chest. After you have the plans, go back to the Bedabin Camp and show Al Shabim (Use the plans on him). He'll give you permission to use the anvil nearby. Enter the tent directly north of Al Shabim, near the magic carpets and use your bronze bars on the anvil to create some dart tips. Then add the feathers to make a dart. You may fail and lose your bronze bar. Take this back to Al Shabim and he will give you some of the darts and the pineapple you need.
 * Start with "I wanted to have a chat?" He will insist that you leave. Next say "You seem to have a lot of books!" He will reply and agree that he does. Now say "So you're interested in sailing?" and he will perk up and say that it's been a passion of his for most of his life. Finally, reply "I could tell by the cut of your jib." Saying this will flatter him and he'll begin rambling off about sailing stories and will be distracted enough for you to unlock his Chest and steal the blueprints
 * Note: You can now make your own darts!

Finding Ana
Head back down into the mine and give the Tenti pineapple to the guard who wanted it. He'll now let you inside. Walk further down into the mine until you find yourself in front of a mine cart. Nearby, search the barrels until you can pick one up as you'll need one later. Then, get into the cart by searching it, and ride it to the other side.
 * Note: It is possible to fail this stunt and take damage.

Once there, go down the north-west path, and you'll find Ana. (Do not talk to her at all or drop her while she is in the barrel, she will alert the guards). Use the barrel on her, then head back to the mine cart.

Rescuing Ana
Put the barrel with Ana in it into the mine cart and send it down the track before getting in and riding down to the other side after her. Search the barrels and you'll automatically find and retrieve the one that has Ana in it ('look-in' doesn't work).

Walk to the winch bucket, put the barrel on it, then the guard nearby will help you hoist it up. Whenever you get a chance, make sure to compliment the guard in some way to avoid being caught.

Head back to the surface again and go to the lift in the southwest corner (Do not take off your slave robes as you will be thrown in the underground cell and forced to mine 15 rocks). Operate it before searching the nearby barrel to retrieve Ana. Then, go put her in the cart nearby. Now, you need to talk to the cart driver.
 * Warning: If you attempt to exit the mine with Ana still in your inventory then the guards will discover her, jail you and you will need to start the Rescuing Ana section again.

In order to get out, tell the Mine cart driver the following phrases: Search the cart and get on it. Bribing him also works, but it costs 100 coins.
 * 2. "Nice cart."
 * 2. "One wagon wheel says to the other, 'I'll see you around'."
 * 1. "One good turn deserves another."
 * 3. "Fired... no, shot perhaps!"
 * 3. "In for a penny in for a pound."
 * 3. "Well, you see, it's like this..."
 * 1. "Prison riot in ten minutes, get your cart out of here!" (You could also choose to bribe the driver instead)
 * 2. "You can't leave me here, I'll get killed!"

Head back to Irena, and she'll reward you for all your hard work.
