Exploration Stage: Abandoned Factory
From: Alicia
Description: The designer's garden is so large that I have yet to see all of it. But the observation deck we are building now has appeared where there was none before. It is definitely there now, though. I am sure the stained glass mad is there too. Let's look for it together.
Completed: You have found a stained glass panel. The pattern was sketched by the designer himself, and it perfectly matches the one on the crystal glass. I think every detail is important in this project. Shall we take a look at the blueprints? I think I've already finished collecting almost all of them.
