"The aqueduct is still not in its original place. How are we going to survive this catastrophe?"
"The challenges are done. But the entrance is locked."
I look up for whatsoever reasons.
There are letters taped to the ceiling. They are secured the old-fashioned way, with wax seals. Notwithstanding, the stamps look futuristic, geometric and symmetric.
I decide to take the letters and read them out loud.
"Congratulations! You have finished all of the challenges and proved to us that mankind is not departed. (Although there were many predictions about the day the universe ends its story. And there is a community based around the idea of the Earth is a circle, not a sphere.)
But don't celebrate your accomplishments too soon, there is still a long-drawn way to go further. For now, this is our presents to you, this viaduct is defying the laws of physics.
Don't be startled. There are crystalline portals, connecting the parts of the viaduct together.
We're just acting around. Actually, everything defying the laws of physics is the railroads themselves. Even when the terrains shift, the trains will be drifting away.
(We know that mankind is fascinated with things that are out of nature, out of the ordinary. Since mystical creatures are too dangerous to be gifted so something more subtle but also more pleasant and artistic, more aesthetically pleasing to look at.)
Another note, English is such a simple language for foreigners to learn. (Although there are many exceptions to everything we learn. And English isn't as illogically and solidly constructed as other languages.)
We spent six months to learn English without any difficulties. Yes, we are more advanced than you. And there are a few linguists in us. But learning a second language isn't hard if you can point out the similarities and differences of your first and second language.
We are sorry in advance if there are parts of the letters that are incomprehensible. There are no exact synonyms in English. And because we are individuals. No individuals are technically perfect. Everyone makes mistakes, even the people invented and created English, even us.
About the tropical rainforest, let it be there. The tussock is better when left untouched. We have built an overbridge for the locomotives. If you want to revisit the island again, you just need to jump to the water. You're welcome there. (There are underground reservations. Currently, it is unfurnished. But you can decorate the conveniences howsoever you want them to be and how the places are for.)
And the greatest gift is the portal on the floor of the lake. We have built an elevator to take you there. You can enter and visit our world. You're welcome there. Currently, we can't speak for ourselves. And we don't want to give away too much information. But our world is just as astonishing as yours.
So you're probably wondering about the fact the government is going to find out. We've got you guarded with more portals and passwords (and optical, auditory and tactile illusions).
At present, there are no passwords, from the aqueduct to the portal to our world. So you have to get to the tussock before anyone else. But the island can be shrunk and put at the workplace, and the people who can do that are you.
There are also cubes that we have put at the workplace. You can take them with you and create portable portals anywhere. But the problem with them is that they are noticeable. So use them reasonably.
Yours sincerely and faithfully,
Us.
Postscript - Enter the bridge, there will be a surprise."
"They are too kind to be challengers, I must say. We don't deserve all of the presents they gifted us."
"I couldn't agree more. They are the most generous individuals I have ever met. But what is the surprise they were talking about?"
"I don't know, I hope they don't use us. But for now, we have to go over the bridge."
