WELCOME TO DESIGNATION EARTH
They came to see Earth.
They came to experience humanity.
They never expected the planet to make them this clumsy.
Somewhere in the far reaches of space, an extraordinary civilisation has discovered the ultimate holiday experience:
Space tourism.
These beings travel from planet to planet, visiting worlds where intelligent life exists. They don't invade. They don't conquer. They don't even make contact.
They simply observe.
And because they are completely invisible, the inhabitants of the planets they visit never even know they're there.
Their gigantic spacecraft is almost impossible to comprehend — a vessel as large as the Earth itself, carrying a population comparable to the number of humans living on our planet.
For generations, this has been the perfect way to explore the universe.
Until they choose their next destination.
Earth.
The aliens are fascinated by humanity. They want to experience our cities, our oceans, our wildlife, our technology and our everyday lives.
But before arriving, something goes terribly wrong.
One particularly clumsy tourist accidentally damages the pollution-detection sensors in the control room.
He doesn't notice.
The ship's systems report that Earth is perfectly safe.
It isn't.
The moment the invisible tourists begin exploring Earth, something strange happens.
They become incredibly clumsy.
Not just a little clumsy.
They stumble.
They trip.
They fall into things.
They knock objects over.
And somehow, whenever one of them loses control of their movements, the humans around them are affected too.
A person walking down a street suddenly falls over for no reason.
A waiter carrying a tray crashes into a table.
Cars collide.
Objects mysteriously fly from shelves.
Buildings begin suffering inexplicable damage.
Entire cities descend into bizarre, uncontrollable chaos.
And nobody knows why.
To humanity, it looks as if the planet itself has gone mad.
But the truth is far stranger.
Earth is full of invisible tourists.
Millions of them.
And they're all completely out of control.
Meanwhile, a small group of poltergeist hunters are investigating strange activity inside an ancient castle. While adjusting their equipment, they accidentally discover something extraordinary.
Their equipment can see the invisible beings.
For the first time in human history, someone can see them.
And even more remarkably…
they can communicate with them.
The aliens explain what has happened.
