This guide will let you know where To Find Nia’s Memories In Xenoblade Chronicles 3. There are 4 locations where you will find memories.
Fornis region
When you enlist Nia as a hero, you will get a quest to find her memories, so you will get the first one in the fornis region as shown in the map.
City interior
The second one will be displayed with a question mark here in the city interior on the map as you know it will tell you about a quest event. But it will not tell you about the particular quest.
Ascension ground
The third one is present here in the Ascension ground and it will come very late in the game. Basically these question marks will appear only when you are close to your party, otherwise all these marks will not appear.
Pentalast region
You will find the final stage here in the pentalast region.
