Physical properties of the hole and comets

Comets
Comets have been a part of the island’s life from the beginning, they orbit in the vast emptiness of space, illuminating the nights and bringing heat to this tiny world. Over time their trajectory and behaviors changed, varying in distance, and ultimately one day, got to where we are now, as comets crash into the hole in the center of the island.

They go in a precise order:

-         The Little Green is the tiniest comet, emitting greenish light and falling quickly.

-         The Flamboyant is the hottest, it is a slow and Yellowish comet.

-         The Radiant is the second hottest and is the fastest comet to fall and has a reddish glow.

-         The Violet Queen is the most natural light and heat source and is of moderate speed.

-         The White Diamond is the one emitting the most light and is of moderate speed.

-         The Pink Pearl is the smallest but more versatile energy source and fall slowly.

-         The Great Blue is the biggest and the last, it is also the slowest and coldest of them all.

Hole
Over time and for an inexplicable reason, the soil around the center of the island became stale, the ground would begin to crackle more and more. And some day, out of nowhere, comets started falling down and crashing at this precise point, and now do so in a predictable and steady manner. A cycle of seven different comets, always in the same order, ending with an enormous one. This created the Hole, an immense crack in the earth, threatening to increase in size. As the comets fell down more and more, the effect they had on the living beings of the island, the flora and the fauna were quite strange. With each cycle passing death seemed to be more and more a distant shadow, life forms regenerated from the constant energy radiating from comets that were closer than ever before. Their absorption by the hole seem to affect growth, fertility and death in a drastic way. Wounds would heal naturally, natural death disappeared, and so did procreation. The world froze. The hole ever intriguing, and seemingly endless is now expanding and the life on the island forever modified.
