Deep inside a fractalaxy called Omicron Perileos. The planet Crillon G3Y, a name which is still disputed, is a terrestrial planet in a huge solar system filled with eighteen other planets. Crillon is about 34.5 times bigger than Earth and its gravity is about 5.73 times that of Earth. A single day lasts 42.42 hours and a year lasts 333 days. The planet is made up of two continents, which make up 89% of its landmass.
Prolog:
Surviving is always high on the list of priorities of any organism, which includes reproducing. The organisms on Crillon have taken this to a gorgeous next level. Almost all of them are bioluminescent. These lights attract animals, who spread the seeds and pollen one way or another. However, perhaps the most intriguing part is that each color or color combination is appealing to different groups of animals, creating an awesome, nighttime eating balance all over the surface. This was 3.14 million years ago.
Now:
500 years after the incident at Eclipsia the technology to create artificial black holes has been perfected. At least that's what science thought. Five centuries is a long time to research. So it was only natural to install a black hole generator when the core of Crillon began to melt. It worked on Eclipsia, too. The side effects turned out to be different than expected.
By this time G3Y had long since grown into an Ecumenopolis, a single gigantic city covering the entire planet. The most important spaceport in the sector. Nearly 21 billion inhabitants. All resources at the limit. The natural atmosphere shortly before the collapse. Then the meltdown.
Two planets or better said ONE planet in double version. At the same place, at the same time. But in different dimensions. Connected by a spiral structure that had formed on the surface. A portal between the dimensions and times. Seen from orbit, the 3.14 million year old jungle with all its luminous creatures was shining through the ultra-modern architecture on the surface. A surreal and unreal sight. Contradicting the known logic.
How can two different versions of a planet co-exist in the same place at the same time? Some questions arose that would keep science busy for a long time. Eclipsia could have been forgotten, but on Crillon Pandora's box was opened. The first seal was broken. At that time, no one suspected that we were no longer alone. We should have looked more closely.
