Quest Walkthrough
1 To begin the quest, answer the message from Serval. Once you arrive at Serval's Workshop, they are bickering about opening an heirloom box from Molly's family.
2 You and Serval get the idea to open the box with a special key. To help, you ask the aid of Pela. Go to the bookstore to find Pela.
3 The clerk will tell us that Pela just left to get some money. Once Pela arrives, return to the workshop.
4 Pela will then decipher the clues needed to open the box. She will then invite you to an Exploratory Excursion. Check out the list of enemies in this Exploratory Excursion here! ▼

You will see a diversion in the paths. You and Pela will split up to find the last clue. The last clue is near a flight of stairs. Use the Home-use Object Finder to look for the final clue.
8 Meet Pela at the bridge. The bridge's control terminal will be disabled. Unlock the control terminal by rotating it clockwise → counterclockwise → clockwise.
9 Rotate the bridge counterclockwise two times in order to get to where Pela is. She will tell you that monsters are guarding the key that they are looking for.
10 Go to the monsters who are guarding the key. Defeat them to finish the Exploratory Excursion.
11 Return to Serval's Workshop with the key. Talk to Molly to finish the quest.
