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 at its simplest you'd essentially be saying "see this black rock? when it burns it makes you sick. you know how it warms your homes/makes heat in your forges/whatever? it also heats the planet, do this enough and it will be too hot to live"
i dont think thatd be exactly intuitive to people who have to burn stuff to survive. what about some kind of cult of ecology that can counterbalance industry & burning things?
