The following page of the guide to AC Valhalla will give you an insight into who Beowulf is and what role he plays in Ubisoft's title.
History of Beowulf
Beowulf is a protagonist of a heroic poem of the same title. It is one of the oldest surviving works of old English literature and describes the prehistory of Scandinavia. This work was written around year 1000.
Hero was born in the territory of today's Sweden and became famous for defeating the terrible monster called Grendel and his mother - antagonists, who ravaged Denmark. Thanks to his achievements, after his return to his homeland, Gautland, Beowulf was crowned king. The hero ruled the land for 50 years, until he confronted a dragon that was inadvertently awakened by one of his subordinates. Although he managed to defeat him, he died from his injuries.
Beowulf's role in AC Valhalla
There will be a mission in AC Valhalla where you can get a closer look at the Beowulf story outlined above. However, it is exclusive content, available to players who will have an active Season Pass. It's probably going to be the only way to have contact with that character.
