A great idea for 'land of the lustrous fanfiction' is to take a character who is not very prominent in the original and make them the main focus. For instance, take Cinnabar. You could write about their struggle in a more detailed way, how they feel being isolated because of their mercury composition. Also, you could create a fanfiction where the Lustrous have to adapt to a completely new environment, like a world with different rules of physics that challenges their very existence.
There could also be new human characters introduced in the fanfiction. These characters might act as catalysts for change in the world of the lustrous. They could be scientists or adventurers who stumble upon the world of the lustrous and their presence shakes up the existing order.
One of the main themes is self - discovery. The characters in the 'land of the lustrous' are constantly trying to figure out who they are and their place in the world. Another theme is about beauty and fragility. The lustrous are beautiful but also very delicate, which shows the contrast between their appearance and their vulnerability.
Starting a 'land of the lustrous fanfiction' can be quite exciting. Firstly, familiarize yourself with the unique characteristics of each Lustrous, such as their hardness, their abilities, and their personalities. This will help you in creating accurate and engaging characters in your fanfiction. Next, think about the setting. Do you want to stay within the known areas of the Land of the Lustrous or create new locations? You can also consider the themes present in the original work, like self - discovery and survival, and build your story around those. Then, just let your creativity flow and start writing your first draft without being too self - critical.
