RWBY's understanding could change in several ways. They could see how fans interpret the power systems in One Piece in unique ways in the fanfiction. Also, they might get a better sense of the world - building, like how different islands are portrayed. They could also start to think about how One Piece's themes of friendship and adventure can be applied in different scenarios presented in the fanfiction.
After episode 1000, it's best to start with the chapter that directly continues the story. You can find this by checking the official manga release or referring to manga reading platforms that provide the correct sequence.
I'd suggest starting from the chapter that corresponds to episode 1060. You can check online manga forums or dedicated manga sites for the exact chapter number.
After Luffy defeated Crockdahl, One Piece's storyline entered a new realm. The following was the development of the plot:
Luffy received the help of White Beard, one of the Four Kings, and went to the central region of the New World to fight against the Red-haired Shanks, one of the Four Kings.
Luffy and the Red-haired Shanks had a fierce battle and finally defeated the Red-haired Shanks to become the new Pirate King.
3 Luffy fought an intense battle with Kaido, one of the four emperors, and finally defeated Kaido to become the new Pirate King.
Luffy had a fierce battle with the navy general, Huang Yuan, and finally defeated Huang Yuan. He obtained a new skill,"Magma Rock" and became the new "Magma Pirate King".
Luffy and the leader of the revolutionary army, Dragon, worked together to overthrow the government of the pirate world and establish "New World's Sovereignism".
Luffy fought fiercely with pirates around the world to protect the rights of pirates and became the guardian of the "pirate world".
7 Luffy finally completed his dream of becoming One Piece. The story of "One Piece" also ushered in a perfect ending here.
The final chapter of One Piece was the final chapter of One Piece, a manga by Oda Shuichiro. The story took place on the stone island at the end of the world. Luffy and his companions fought fiercely in search of the legendary One Piece treasure and finally defeated all the enemies to realize their dreams.
At the end of the story, Luffy and his companions finally arrived at the legendary location of One Piece's treasure, the New World. However, they found that the treasure had been guarded by a place called Demon Island. On Demon Island, Luffy and his companions faced more dangerous tests, but they persevered and finally defeated all the guardians of Demon Island and obtained the treasure.
At the end of the story, Luffy and his companions finally returned to their hometown, the hometown of "One Piece Island" Monchi D. Luffy, and began a new journey.

I can recommend you the following two completed One Piece Doujinshi novels: One Piece: The Strongest Vice-Emperor Mr. 3 and One Piece: The Ghost of the Dark Fire Spear. The former was about Mr. 3, who had transmigrated to the world of One Piece. Through his own efforts, he finally became the king of the pirates. It was a relatively long novel with a total of hundreds of thousands of words. The latter was about a male protagonist who robbed pirates in the name of justice. He started a story that overturned the balance with the pirates. The number of words was also relatively rich. I hope you like this fairy's recommendation. Muah ~😗
