You will be heading to the Atlantic Forest, located in Brazil, South America. The rainforest has been facing illegal deforestation efforts, which are not uncommon in and of themselves, unfortunately, however this case is a bit unique.

It seems their 'work' has disturbed an area of the rainforest where dryads have made their home, and a result, they're recklessly slaughtering nature spirits with no regard for the life they snuff out. You will need to find way to halt their efforts: temporarily at first, before the forest dwellers start fighting back and we turn this into a war. And then you must find a more permanent solution, perhaps negotiating with the company responsible, to make them understand what they are doing and why it must end.
