20 Megastructures

Roll (d20):

1. A labyrinth of mazes, reaching deep into the earth. It is said that if you can find your way to the centre, you can have any wish granted.
2. A tower that stretches from the bottom of a very deep pit, all the way to the top of the sky. It is said that if you climb to the top, you will be able to see the future.
3. A vast desert, stretching as far as the eye can see in all directions. In the centre is a small oasis, and it is said that if you drink from the fountain there, you will be able to see the past.
4. A giant clock, perpetually resetting itself to zero. All who look upon it fall into a deep sleep, from which they never wake.
5. An array of enormous mirrors, orbiting the sun, which reflect and magnify its light, making day and night unnaturally bright.
6. A crystal palace, in the middle of a great desert. It is said that if one breaks even the smallest piece of the structure, the entire palace will shatter.
7. A city, contained within a single, enormous glass bottle. The citizens are said to be under a powerful curse, dooming them to live out their lives inside.
8. A staircase, leading up to the sun. Each step is made of a different kind of metal, and no two steps are the same size.
9. A library that contains every book ever written. It's possible to get lost in here for years and never find the same book twice.
10. A cathedral made entirely of glass. The stained glass windows show scenes from other worlds.
11. A vast white city, so beautiful and perfect that it is said to be the work of angels. It has no doors or windows, and no one has ever found a way in.
12. An island that is the home of a giant tree. The tree is so big that its roots form mountains, and its branches provide shelter for an entire city.
13. A tree, as big as a mountain, with a trunk made of stone and leaves of metal. It is said to be the first tree, and the source of all metal in the world.
14. A palace, made of a crystal so clear it is almost invisible, that contains the throne room of the queen of the fairies.
15. A black pyramid, miles on a side, built on the edge of the world. It grows larger every day, threatening to consume the world.
16. A thin metal rod, a million miles long, that stands upright. At the top is a small platform where a single person can stand.
17. A transparent orb the size of a small planet. It is completely empty inside.
18. A lattice of powerful magical crystals, embedded in the rocks of a mountain. The mountain is slowly growing as the crystals absorb magical energy from the surrounding area.
19. A flat mirrored plain, a thousand miles across, and perfectly flat. Thought to be created by god, so they could see their reflection.
20. A city build on the back of a giant turtle, that slowly swims through the planes, stopping at other cities to trade.
