WMG / Vinland Saga

Hjalti Gardarsson is alive.

The son of Gardar and Arneis is actually alive and will return to seek Vengeance upon Ormar, Snake and all the other in the Ketil Household.

Canutes story will culminate with the Battle of Helgeå.

It was basically the last failed attempt by anyone to stop the expansion of his power. Norway and Sweden had to pull an Enemy Mine just to challenge him, and it failed. After that he was the supreme king of "England, Denmark, Norway and some of the Swedes" as he himself put it.

The setting will eventually shift to North America.

It's right there in the title, after all.

Many chapters post-timeskip, pretty much confirmed that they will at least try to go there.

Thorfinn will die in a similar way to his father.

Killed by Skraeling arrows.

Einar is the same one from the Icelandic sagas

The party is headed for Iceland already. But, then Einar will also reunite with his own family. Then he will make an oath with Bishop Arnald in exchange for help with the expedition to Vinland. And then Arnald will call in the favor before the party is able to set sail again...

This would also fit in with the manga's theme of violence vs. non-violence. Einar hasn't achieved the same level of enlightenment as Thorfinn, so he would be willing to kill for an oath.

Once (If?) the party reaches Greece, they'll meet with the Varangian Guard.

It would be interesting to have the party travel so far from the Norse lands only to meet up with the norse yet again in Byzantium.

Thorfinn and bug-eyes Thorfinn will become a Composite Character in the sagas

Why else would there be two Thorfinns? While main Thorfinn is the leader of the Vinland expedition, Bug-eyes will beget a son with Gudrid, the first Norse child to be born in America. Main Thorfinn will hook up with Hild instead.

The anime will at least use Amon Amarth for an opening theme

It's an anime about vikings, they're a band that sings about vikings. It's a match made in Valhalla!

• Sadly jossed

Thorkell will join Thorfinn's voyage to Vinland

The real Thorkell the Tall all but disappeared from historical records in the middle of Canute's reign. Given that he had grown bored of an increasingly pacified North Sea Empire, it's not exactly a stretch for Thorkell to abandon Canute and join his Great-Nephew's journey to Vinland, if only for an opportunity to find something to fight and serving as a Token Evil Teammate of the crew. He may even go out in a blaze of glory fighting off a horde of Skraelings once the settlement comes under attack
