Akka di Kebnekajse commands a migrating wild geese flock across Sweden. Her name, echoing Sweden's highest peak Kebnekaise, reflects her prominence and authority. An old, gray goose with intensely shining yellow eyes, she possesses deep experience in animal behavior and survival tactics.

As matriarch, she initially regards outsiders with skepticism, especially the domestic goose Morten seeking to join. She demands proof of flight capability, demonstrating her no-nonsense leadership. Her reluctance toward the miniature human Nils Holgersson lessens as he proves reliable through trials.

Her background includes discovering and raising Gorgo, an orphaned eagle found in an empty nest. She taught him to survive on fish instead of preying on birds, especially geese, showcasing her mentorship across species. This upbringing forged a lasting bond despite their natural predator-prey dynamic.

Throughout the journey, she serves as a wellspring of wisdom, offering guidance on the natural world and animal ethics. Her interactions with Nils foster his moral development, instilling empathy and responsibility toward creatures. She maintains a pragmatic approach to danger, prioritizing flock safety during encounters with the predatory fox Smirre while acknowledging Nils's growing usefulness in outmaneuvering threats.

A key demonstration of her development occurs when she recognizes an act of empathy from Mr. Smirre Fox, revealing her capacity to see moral complexity in adversaries. Her decisions consistently prioritize the flock's welfare over individual interests, cementing her role as a protective, strategically minded leader. Her extensive knowledge of Swedish landscapes and animal societies makes her an invaluable navigator for the migratory journey.
