In the remote forests of northern Maine is a mist-shielded valley called Valhalla, where an ancient Viking society has secretly lived for centuries. Usually, this valley is protected by the proud warrior Valdemar and his giant falcon, Skagerrak, but today Valdemar is being held by police in nearby Fort Kent, for attacking a group of state legislators at a town hall event! What could drive the normally reclusive Viking to strike out like this? And how does it relate to urban development and child labor? Putting things right in Fort Kent might put both Superman and Clark Kent at odds with the law!
