!!Specific Trivia
* Askeladd(en) is the main [[TheHero hero name]] in Scandinavian [[FairyTale Folk Tales]]. He's the protagonist and/or male Cinderella (Askeladd meaning Ash Lad. Website/TheOtherWiki [[http://en.wikipedia.org/wiki/Askeladden can tell more about it]].) But the Askeladd's friends in the folk tales are usually badasses.
* In history, Thorfinn Karlsefni is a descendant of the legendary Ragnar Lothbrok, arguably ''the'' most famous Viking, through his paternal line and Ragnar's son Bjorn Ironside. Ragnar's other son, Sigurd Snake-in-the-Eye, settled down in Denmark and had descendants that eventually continued to King Sweyn Forkbeard and Canute. This means that albeit very distantly, Thorfinn and Canute are cousins!
