Just found this on Netflix
Very well made and the style reminds a bit of some studio ghibli movies.
Its quite historically correct with many details, and people actually act in a way that would work back then.
Also the traveler “Leif Ericsson” is in a few episodes…
He is the viking who found america around 1000ad, long before Columbus.
The name Vinland is actually what he calls “The land in the west without war and slavery”
