What are the skills and knowledge you could actually bring & fully realize at some point in the past?
And we're taking this in the strictest, nerdiest, materialist lense. I don't care how smart you are you ain't making a steam engine the in bronze age, for instance.
So what could you create, with just your knowledge & period tools? What kind of institutional, technological, philosophical innovations could you realistically recreate? How would you interface with the social fabric of society to not be some crazed pariah who never positively influences the place they went?
I think that was mostly an Aztec thing. The indigenous people the Vikings met were nicer to their kids than most people are today and AFAIK they didn’t do slavery or human sacrifice.
There are remnants of slave labor camps by what pop culture would call Vikings.
I think they mean the Viking human sacrifice, which did happen.
