[ WP ] The Fourth Wall has been breached and our world has come into physical contact with previously fictitious realities . What happens next ?

On April 5, 2043, the Fourth Wall fell. It only took an instant, but in that instant everything we thought we knew changed forever. 
 
 We had n't even known the location of the wall. But reports started coming in. Farmers in a remote part of Missouri told of unspeakable horror. Of daughters kissing a young scoundrel. 
 
 We did n't believe at first. Oh, but we were fools back then. A small search party of local law enforcement was sent. The National Guard was n't even called in. We should have just thrown the Navy Seals, Israeli commandos, British SAS, the whole book at them right from the start. Or closed the damn thing off again. 
 
 The search party never came back. That's when the press started taking it seriously. A few crazies talked of UFOs and Loch Ness monsters, but that's all they were. Crazies. The truth was much worse. 
 
 After a few weeks, and a few more disappearances, the Guard got called in. No word was heard. 
 
 The world began to descend into chaos. Grocery stores emptied. Revolutions erupted. A border skirmish broke out between China and Russia. We were on the brink of total madness. 
 
 A meeting was held. The United Nations gathered. For once, they were actually united, with one voice. An expeditionary force was assembled, the UN's finest. This time, three men made it back. Every one of them ranted and raved, about thatchers and berries and gathering wood for the fire. Unrelated things. We threw them into insane asylums, where all three took their own lives. 
 
 War was declared. A real state of emergency for the known world, unlike any seen since the Black Death or the Mongolian conquests. Entire armies went forth. The world's best military minds were called out of retirement. Former world leaders called for calm minds to prevail. 
 
 We heard not a word from the armies, drones, and weaponry that disappeared into the breach. But as the waiting troops outside watched, from that horrible gap in reality came one lone boy. He was dressed like a 19th century country bumpkin or farmhand, a little disheveled and dirty. A mischievous smile spread across his face, spelling doom for our world. 
 
 I write this as of May 7, 2051. I have been whitewashing a long fence, the new Third Wall, for many years. I grow tired, but I can not stop. If you are reading this message, put in earplugs, the best ones you can find. Glue them to your ears. Pursue the boy. Kill him. Save the world.
