XiDong12, also know as the Life planet, was cooling down. It was as much a cause of concern as one of bewilderment. Over four billion years, it was the sole source of heat in a universe riddled with bone-numbing frost.

The planet itself was uninhabitable, but it kept the two moons orbiting it warm enough to support life.

We, the human race, had unexpectedly found our way to it through a wormhole just as our world Earth1.0 was on the verge of collapse.

It was our third chance. We knew that it might be our last.

We had learned from our mistakes.

Thus, three thousand years ago, when humanity had set foot on the two moons of XiDong12, they had vowed to protect their home. Now and forever.
Our ancestors had done everything in their power to keep the climate and the ecosystem as they had found it. And we had followed in their footsteps. All our inventions facilitated the enrichment of the environment.

Sickness, war, and poverty were no more terms that the younger generation was aware ever existed. Everything was perfect, and humans felt that finally, they could rid themselves of the fear of extinction.

Alas, sometimes, even after doing everything right, life may not turn out the way we want.

The first time I heard about the Life planet losing its heat, the question I asked myself was: why that which had been going strong for billions of years had suddenly decided to betray us?

We brainstormed. Everyone, irrespective of the field of expertise, who had anything to contribute, was given a chance. Luckily, everyone listened when Ren spoke, even though she was just a kindergarten teacher.
Humans had evolved. Now we spoke, only if we had something to contribute towards the greater goal. No one did it to show their greatness or to put others down. No one interrupted others just because they could. People who flaunted their power were frowned upon by everyone. We had learned the hard way that to find solutions, we needed to hear people's voices. None should be discounted or disregarded without reason. That was what the destruction of our first two previous homes had taught us.

Ren's idea was simple yet effective. Five high-density, heat-resistant probes encased in Gix ice imported from planet XiDong9, the coldest planet in the universe, were created; two were high speed, destined to enter the heart of XiDong12; three were larger. They were capable of covering more ground. These guided into its atmosphere. Immediately, the reason for the drastic fall in the temperature came to light.

The core's RPS (rotations per second) had dropped to 1/3. Remnants of an unidentified metal of alien origin were found in its upper atmosphere as well.
The implications were clear. Someone, possibly another civilization from a different dimension, had found a way to reach XiDong12. One that hadn't learned its lesson.

We couldn't afford anything to disrupt what we had created. And if that meant not sharing the moons, so be it.
Within days, we had located the location from which the unidentified metal had entered XiDong12's atmosphere. A day after that, we had destroyed the passage: the wormhole.
With the external threat eliminated, we turned our attention to restoring the core's RPS to its original speed. Without losing time, we dedicated all brains to what was of foremost importance: survival.

Humans have the power to achieve everything if they put their minds to it. And this time, the best of them were at work, listening and growing, unhindered by the things that had left us homeless not once but twice.

A weapon was created not to destroy but to restore, to mend that, on which our survival depended. Together- a civilization working in sync- we did what we had set out to do.
