So, I have something of a problem. I have a story concept that takes place more or less in the real world, except that humanity has been given access to a whole bunch of magical abilities by an unknown entity that by all appearances seems to have no motivation for it beyond hiding behind a rock and watching the fireworks. So now humanity is adjusting to living in a world where humans can teleport, turn invisible, wall cling, summon spirit animals, ditch the human race entirely and become members of entirely new humanoid species, and much more. In addition, every once in a while, society has to deal with week-long events where the unknown entity basically challenges the whole human race to various deadly challenges, like a week where humans fall west while everything else still falls down. You may have noticed a recurring theme with all of these: they're all global events. And that, naturally, means they affect every aspect of daily life for every town, every city, every country on Earth, meaning that in some shape or form all of these implications will impact the lives of my main characters since they don't live under a rock. Which means I have a huge responsibility to catch as many of these less-obvious, but very big implications for my world's setting as I can, and a lot of the time this is a very intimidating and difficult task. So I was wondering if anyone had any experience they could share for how they make this more manageable, or if anyone has any strategies for making it easier to think about and catch big worldbuilding implications. Because as it stands I'm worried I'm going to not only get something horribly wrong, but that the thing I got wrong will stress suspension of disbelief or, even worse, might have been a way more interesting angle to approach the event from than the more small-minded, obvious concept I had to begin with.
