In Quern - Undying Thoughts, near the end there's a puzzle which you can solve only if you collected all the letters throughout the game. So I wonder what happens if you didn't collect them?

According to Steam community, somebody posted the same question which was answered by a developer:
What happens if you reach the library without reading/obtaining the letters?
They magically appear in your backpack as you step into the library ;)
