The film is loosely based on the real travels of Ahmad Ibn Fadlan, a 10th-century Arab traveler and chronicler. However, the film takes significant liberties with his historical account, adding fictional adventures and characters.

The Norse warriors are not based in historical characters. Some of them are however inspired by characters from the Beowulf epic. This includes Buliwyf.

The film includes a 'seeress' character who provides cryptic prophecies and guidance. While Viking society did have individuals who fulfilled similar roles, the film's portrayal of the seeress is likely exaggerated and more fantastical than realistic.

While Ibn Fadlan did encounter Vikings during his travels, the film's portrayal of their culture and customs is a blend of historical accuracy and Hollywood embellishment. The film captures some aspects of Viking society but also relies on stereotypes and dramatic license.

The film's portrayal of the 'Wendol' as monstrous cave-dwelling cannibals is entirely fictional. There is no historical evidence to support this depiction. The Wendol are likely a fictionalized representation of various groups encountered by the Vikings.

The film's climactic battle against the Wendol is a fictional creation. There is no historical record of such a battle or of Vikings encountering creatures like the Wendol.

The film depicts a growing bond of respect and friendship between Ibn Fadlan and the Vikings. While this is a central theme of the film, it is a fictionalized element added for narrative purposes.

The film attempts to portray some aspects of Viking culture, such as their warrior ethos, their seafaring skills, and their social customs. However, some details are inaccurate or exaggerated for dramatic effect. The film offers a romanticized and somewhat stereotypical view of Vikings.

The film incorporates some Old Norse language, which adds to the authenticity of the setting. While the accuracy of the pronunciation and vocabulary may be debated by experts, the inclusion of the language is a positive element.

The film's portrayal of Viking weaponry and armor is a mixed bag. Some elements are accurate, while others are more Hollywood-ized. The film's focus is on visual spectacle rather than strict historical accuracy in this regard.

The film incorporates some elements of Viking rituals and beliefs, such as their funerary customs and their belief in fate. However, some aspects are simplified or misinterpreted for dramatic effect. The film's portrayal of Viking religion is not entirely accurate.

The film's portrayal of Viking longships is generally accurate in terms of their basic design and functionality. However, some details may be stylized or inaccurate for cinematic purposes.

The film's overall tone is one of adventure and heroism, with a focus on the clash of cultures and the overcoming of adversity. While this is entertaining, it also simplifies the complexities of the historical context and the characters involved.
