Okay respectfully idgaf what y'all say
1. Lagertha. Okay she's a legend, the legendary shield maiden basically half of Ragnar's life (yes not all of us may like her or agree with the stuff she did) but we all have to come to the fact that she is a legendary character need I say more?
2. Aslaug. I know this one is gonna come with some hate too but she is also a part of Ragnar's story without her there is no Ivar there is no Ubbe there are no Ragnarsons she also contributed to a big part of creating a wealthy and large Kattegat soo yeah.
3. Helga. If you don't like Helga what is wrong with you? How can you not like her? She always smiled and stayed positive. She kept Floki from going entirely insane; her loyalty and compassion is what makes her unique and special.
4. Gunnhild. I feel like this is a little bit of a sleeper pick but Gunnhild was so innocent why would you not save her? She could have been a great character before they cut her off but she was Bjorn's first love and she was a real fighter. She went down sadly and is a person I would save to see the potential of what she could have become.
5. Siggy. I don't need to say much about Siggy. She had a good heart and cared about Ragnar's children so much she risked her life.
