When you enter Advent for the first time in chapter one, you should see a Gilded Door somewhere to the east. Here’s how to open it.

How to open the Gilded Door in Advent

To unlock the Gilded Door, you’re going to need theMagical Key. It’s found in a chest inside the Musty Tower on the Eastern Peninsula of the main continent, which you can only climb in chapter five.

You need the Magical Key to open the door on the Musty Tower’s roof and move the main story forward. However, as its description reads, it can be used to open any door—including the locked one in Advent.
