The month witnessed a change in the other world as well, the great Viking era was coming to its peak as warriors and prophecies backed this up.
Bjorn had grown to be a great warrior, he was strong with a sense of justice to boot.
He saw betrayal as the ultimate sin, and now Ulf had shown his true color by coveting someone that did not belong to him.
Bjorn had an army under his command and their loyalty to him was absolute, they would jump on a sword for him if he willed it because they knew the honor that came with serving the son of Ragnar.
Viggo was one, he was a rough person that did not follow the conventional rules but he was no criminal. And listened to the laws but the morality of others did not apply to him.
