the fascinating arrangement of solar system

The solar system was once home to a remarkable total of 17 planets, all gracefully orbiting a colossal sun. In the distant past

For now only 15 planets remain, Two planets were merged forcefully; (one planet was devoured by the sun)Arita was one of them and the other was named Devsuna, the planet where all the monsters resided. The power level of Devsuna was so immense that it completely destroyed Arita's population, solely because Devsuna was the last planet in the solar system.

The inhabitants of devsuna didn't get proper food, and for water, there were only frozen lakes, or even the sea was frozen. They had to eat ice cubes to feed their bellies while enduring excruciating hardship daily. However, fate took a drastic turn when Devsuna fused with Arita. That day, the monsters of Devsuna didn't hesitate to eat the other living beings of Arita, the barrier was established too late; 75% of Arita's population was wiped out in mere three days.

The monsters simply couldn't control their hunger and were driven to madness . Some didn't survive the Harsh sunlight that they had seen for the first time in millions of years.

That was the time they called the golden age of Devsuna; for Arita, it was their worst nightmare.

The losses were so extensive that the remnants of Arita's civilization's advancement were thrown back by centuries.

In this solar system, planetes boasted unique species, advanced technologies, magical innovations, and distinct ecosystems.

One planet, however, met its fate by being wholly consumed and obliterated by the sun.

Many things were common between planets, but the most common and dangerous was that every planet had at least one teleportation portal through which they can go to other planets.These portals served as vital conduits for sharing knowledge, yet some planets misused their power, engaging in interplanetary conflicts.

Note: planets had to await their neighbors alignment for teleportation.

Arita was also one of the planets that shared their knowledge about magic and many essential infrastructures for stable living; however, in the end, Arita lost their portal location. During the merge they were unlucky and lost it.

But the monsters of Devsuna didn't know how to use their portals and was completely cut off from the teleportation lines from the start, which was also the reason many other species from other planets survived until now.

Note: The average lifespan of an Arita human was 200 years.

while Devsuna's monsters lived an astounding 2 million years of lifespan.

As for the other species, they had their own different lifespans.
