In Brazil

Well

As a person from modern times – From AFTER the Americas came into contact with Europe, if I went near a person here in the Land of Palms (that’s what the natives called Brazil!) from those times we’d both get horribly infected and die a lot due to how antibodies work. Viruses did a lot of the legwork in genociding the natives.

The place I currently live in is slowly turning into a desert, but was a deep jungle back then.

… I think I’d just die? Become food for a jaguar or sth.

Would love to indulge in the fantasy of giving the Guarani people guns and a warning to shoot white people on sight just to see how history would change, but that ain’t happening.
