Just read "Rainbow Factory". Glad I did. Now I KNOW that I need to write my story. Such an amazing song deserves a fanfiction based on it that isn't complete horseapples.
No gore in my story. There's no need for it. Gore isn't shocking, especially in the written word. At most, it can gross out the reader if it is written descriptively enough. My goal isn't to make the reader sick, it's to enthrall them.
