Rather than calling it an order or a mission, I'll give you something fun and interesting.

This is a Treasure Map, but it's covered in different colors so that I can't see what's underneath. I'm sure it indicates where something is hidden.

It is your mission now to uncover the secrets of this Dirty Treasure Map.

First, go see Betty in Ellinia. She'll be able to offer you some help.

Oh, you've completed it!

The results could have been better, but I'm sure you've grown stronger in the process. Well done!
