Amethyst Apocalypse

On a gloomy dusk in the year 2718 of the world calendar, an unprecedented and strange black rain fell silently, quickly covering every corner of the world. This black rain was no ordinary precipitation, but carried some unknown mysterious power. As the raindrops penetrated, a group of infected people suddenly appeared in the world who were attacked by strange diseases. These infected people have undergone a transformation. They have gained the ability to control extraordinary power. Whether it is controlling light energy, mutating into monsters, or splitting space, all kinds of incredible abilities are revealed in them one by one. However, there is something hidden behind this power. The cruel price is that with the frequent use of abilities, the infected person's body begins to mutate and is gradually eroded by a deep amethyst. It will eventually completely transform into a cold crystal. People have given this strange disease a loud and tragic name - "Amethyst Syndrome"
