In Shadows of Valentia, collectible objects called Memory Prisms help flesh out the game's story by showing scenes from the main characters' past.
How to collect Memory Prisms
Memory Prisms can be found in the environment using the "Examine" function when exploring various areas of the game. Often they are found within dungeons, strongholds or keeps that have been cleared, or elsewhere. The more Prisms you collect, the more memories you'll be able to view.
Watching Memory Prisms
To view a Memory Prism, you'll need to access Mila's Turnwheel. This can be done from the main menu using Mila statues in the game. For more on Mila statues, read How to Use Mila Statues.
