Der Gesprungene Kristall

The magic feels so integrated into the world, but I'm curious how much of it was driven by the story versus world-building needs. Did the magic system evolve during writing?

There was a lot of setup and character development, which made the action scenes stand out more. Was this deliberate to build tension or just how the story unfolded?

The icy, treacherous landscape added so much atmosphere. I wonder if the author drew from real-world environments or created it purely from imagination.
