The concept of honor is a significant theme as well. Vikings placed a high value on honor, and in 'the broken sword' novels, characters may strive to uphold their honor, even in the face of difficult decisions. This could involve loyalty to their clan, keeping their word, or avenging a wrong. The broken sword itself might symbolize a loss of honor or the need to regain it through heroic deeds. Additionally, the theme of the struggle between good and evil is common. There are often dark forces at work, such as evil sorcerers or malevolent spirits, and the heroes must fight against them to protect their people and restore balance.
Another important theme is the role of magic. In the Viking fantasy context, magic might be intertwined with the Norse gods and mythology. For example, a broken sword could be a magical artifact with special powers or a symbol of a broken covenant with the gods. The exploration of this magic adds an element of mystery and wonder to the story. Also, the theme of fate is prominent. The Vikings believed in fate, and in these novels, the characters' destinies are often shaped by forces beyond their control, whether it's the will of the gods or the consequences of past actions.
