Napim

They know not of their origin, nor their purpose. But nature remembers all - even the deep sea. It remembers the day when the seafoam inexplicably sunk to the very bottom of the ocean, slowly but surely consuming everything living it met on its way down. Nothing escaped the gruesome death, nothing that stood in the way of the sinking foam. When the descent was finished, and the foam, which was still quite minuscule despite the amount of sustenance consumed, finally touched the first grains of sand, a small conch revealed itself from under a pile. The seemingly sentient foam bounced over and pushed itself into the conch. And then it rested.

And rested.

And didn't move an inch.

For years. Decades. Centuries even.

If anything around cared, it would think that the conch is just a remnant of something long gone.

But on that fateful day, the conch moved. After a short while of trembling, the conch exploded, and after the dust had settled, all that was left was a tiny humanoid fish. The bottom of the sea hides an unthinkable amount of wondrous creatures that a human wouldn't believe to be real, but the way this small fish grew over the years was truly unbelievable.

This is the form that Napim possesses right now. They spend their long days traversing the endless sand, occasionally interrupted by a boulder or a reef. They are respected by everything alive around them because everything they touch is gruesomely eradicated and eaten. They care not about this, nor do they think about why this is happening. They do not understand the concept of emotions and they only accept what happens around them, because that is the way things have always been. This has been their journey so far, and this is how it's going to be till they cease to exist and, perhaps, disintegrate into more seafoam, repeating the cycle, forever, as long as the Earth spins around the Sun.
