Frozen 2. El bosque de las sombras

The story adds so much depth to Iduna and Agnarr's characters. I wonder what inspired the author to focus on their origins and how much of the lore was mapped out beforehand.

Learning about Iduna's past and her magic made me see the characters in a new light. Did this backstory change how others viewed the Frozen story overall?

The narrative felt like a mix of adventure and emotional depth. I'm curious if there were specific storytelling techniques the author used to balance these elements.
