The prologue summary that I ignored because the project was somehow deleted, anyway, in short, Diana came to a party that everyone came to except Sapphie because she was asleep, Diana shrunk Ruby and Garnet and put them in a box and left the party, everyone was terrified and decided to go to Sapphie to tell her what happened, Peridot volunteered to go and tell Sapphie, and when Peridot woke Sapphie up and told her everything, Sapphie got angry and decided to punish Diana in her own way, so Sapphie went to the party to find a sample to guide her to Diana, she found a hair from Diana's fur, then Sapphie analyzed the sample and led her to Diana's dark kingdom, and back to our current story, Diana arrived at her kingdom and was feeling sleepy and was not paying attention to what was going on around her, Sapphie appeared and launched a direct attack on Diana's tail, but why did she aim her attack at Diana's tail exactly? Well, all I can say is that it will be continued later at another time...
