How Did Crystone Lose The Grime

The planet Crystone is a host to all sort of gem based life forms that all work together in order to preserve the planet’s clarity. Clarity helps keep the planet, as well as the gems inhabiting it, running and Crystone’s clarity is so strong that it helps drive away the Grime, which is a kind of muck that can affect all gems. You see when gems get dirty they begin to lose their clarity and as they lose their clarity they begin to lose their shine and become lifeless rocks. One day a black crystal fell from the sky and impacted itself into the ground. No one thought anything of it as crystals of all shapes, sizes, and color always landed on Crystone so they just continued on normally. There was only one gem who thought the black crystal was weird and his name was Diop. Everyday he would walk past the crystal and examine it wondering what it was about. People would pause and tell him that he is worrying over nothing but he was not so sure about that as the crystal made him feel nervous every time he got close to it.
No one believed him except for his friends Ami, Di, Ru, and Rho. The very next day something black was leaking out of the crystal and someone went closer to it to examine it. As soon as they got close the black goo attached to them and drained them of their clarity. “Run everyone it’s the Grime!” yelled Diop. The Grime exploded out of the crystal and started capturing gems left and right turns out the crystal was leaking Grime all the way to the center of the planet and had drained it’s clarity. Diop and his friends manage to escape and know must find a way to restore Crystone’s clarity. Ami suggest going to the different altars on Crystone and cleaning them to help restore their clarity. Everyone agrees and on they
