This is unrealistic, but what if we had to go against the nation of Fontaine to recover Sandrone's body and repair it? It could all start with Arlecchino receiving the news that it was decided by Fontaine's court (Neuvillette) that Sandrone's body is going to be pulverized or destroyed in some way. (Also, Freminet has learned from reading Sandrone's work how to repair Sandrone).

Arlecchino would tell the traveler this, and we would head to Fontaine to negotiate with Neuvillette, and for the first time, we are denied by one of our "friends." Remember, we want to save Sandrone, because she saved our lives by jumping in front of the dagger the Dottore threw.

Arlecchino starts to put a plan together and calls our Nod-Krai friends for help. Meanwhile, our Fontaine friends would be trying to convince us that Sandrone is evil and stuff because she is Fatui, whatever. The two final convincing factors that convince the traveler to go against Fontaine are Furina and Varka, because Varka just seems like that kind of dude, and Furina needs more screen time.

Then it begins, and we end up in a boss fight against Neuvillette. It becomes the classic, we are beaten up at first. and then our heroes, Arlecchino and Columbina, come to the rescue. Then we invade the prison where Sandrone's body is being kept with the trio of Knave's kids. We recover the body, and Freminet and Aino fix Sandrone up.

Welp, this was my idea! Any thoughts? Ideas? Your own stories you would want?
