Boreal

Sira is a lonely child whose mother is increasingly distant, so she spends most of her time at her grandmother's house.
One day, Sira is on her way to her grandmother's when she suddenly gets lost and finds herself in the magical land of Boreal. She is confused because she doesn't know where she is but it turns out that she is expected.
The Queen of Boreal tells Sira that imagination is disappearing from the world of the humans and that one day there will be no stories left. Sira is the only one who can help them.
