2. Gale will direct you to Petra at the Research Center for a diagram of a Removable Battery. Collect TBD Data Discs and go see Petra.

3. After you have given her the discs, she will promise to provide a diagram soon.

4. If you speak to some of the townspeople, you'll learn about the things that were stolen from them:

5. Petra will send you a letter with the diagram.

6. Collect the necessary materials and assemble the Removable Battery.

7. Bring it to the cave on Amber Island. Liuwa will be waiting at the cave entrance. If you have the Removable Battery with you, he will allow you to enter.

8. Hostile creatures have taken over the cave. Defeat them as you explore the cave. Be sure to collect any random items you find on the floor; these items belong to citizens of Portia and you will have the opportunity to return them later on.

9. Explore until you discover an enemy boss, a large Snaillob. Defeat it and continue on to the generator room. If you have taken damage, make sure to interact with the small soup pot cooking over a fire to restore your HP and Stamina. Place the Removable Battery and repair the generator. The exit will be blocked and you will be ambushed by rat thieves. Defeat them and continue through the new doorway that has opened. Explore the cave and defeat the rats, collecting the items the rats stole as you go. Make sure you have a Power Stone with you to start up a depleted power generator along the way.

10. Eventually you will enter at the upper level of a large room, with a large rat and other rats on the lower level. Interact with the soup pot here on the upper level, and consider leaving the cave using the glowing light that is also here on the upper level. You will be able to return to this exact location at any time if you do choose to leave. When you are ready to confront the rats below, drop down to the lower level.

12. Report to Gale. He will reward you with experience, gols, and workshop rank points.

13. After the mission is complete, you won't be able to enter the cave on Amber Island for a while. When you try, Liuwa will stop you:

13. Head to town and look for the people who had items stolen from them.

After the mission is complete, Gale will tell the townspeople:

The following story will also become available from the Portia Times:
 * Portia has been hit by a crime spree recently, with many items stolen. The Civil Corps was having trouble figuring out the suspects, some even suspected the usual criminals Huss and Tuss. On a stroke of luck, Builder (player character) found and defeated a band of bandirats within the Amber Island cave, including their leader the Rat Prince. Most of the items have since been recovered. According to Civil Corps officer Arlo: I must commend (player character) for taking action, the Builder defeated all of the bandirats, we just scared off the rest. With these actions, hopefully the bandirat gangs will never bother Portia again. -The Portia Times, "The Prince of Thieves", reported by Erwa
