Land of the Lustrous

Years ago, six meteorites struck planet Earth, which resulted to creating six moons and leaving a solitary island in their wake. If someone was unable to make it to the island, they sank deep in the oceans and would slowly become a crystal. 28 of these crystallized lifeforms, also known as the Lustrous, rose from the bottom and resided on the island. Now, they must defend themselves against the infinite number of Lunarians, which are inhabitants from the moons who want to harvest their bodies to craft weapons and jewelries.
