Secondary characters
All figures you can see below are actually not mentioned in the original story. I added them to clarify specific parts of the plot.

The dormouse is living in an old stump on the wild fields. It’s interacting with the warrior as a part of nature in the animated sequences of the movie, where I don’t show the fields.

The warrior is building a scarecrow of his armor. This should show the point when he gets really deep into nature and detach himself from former behaviours.

I choosed the crows to be a recurring symbol for nature and also used them once for changing the narrative level from the animated sequence to one of the cross-fading parts in which the fields appear.
