A) Nothing, just totally naked
B) What you’re wearing and anything you carry with you (even if you’re not carrying it right now) like a bag
C) What you’re wearing, what you carry with you, and the contents of your home (it will be teleported within a few hundred metres on the surface in an accessible location, but obviously won’t be connected to any services like electricity or water)
A) Assimilate with the local people and probably be fine. Eventually use my wide, but mostly shallow knowledge on many subjects to start a scientific revolution and try to repel the Spanish-colonial shithead christo-fascists.
B) Assimilate with the local people and probably be fine. With the help of my smartphone and multi-tool; use my wide, but mostly shallow knowledge on many subjects to start a scientific revolution that will hopefully help repel the Spanish-colonial shithead christo-fascists.
C) Assimilate with the local people and probably be fine. With the help of my smartphone, multi-tool, and various technology examples of the common era, start a scientific revolution that will likely help repel the Spanish-colonial shithead christo-fascists.
In any of these scenarios, I would try to warn people about the Spanish-colonial shithead christo-fascists that are coming to fuck their shit.
