Here's what I planned for the story if I continued it;
The past Straw Hats come back, then they'd journey into Alabasta after someone had heard something about a Devil Fruit user that can control time. Eventually the Straw Hats find a woman in a small town. She ate the Mirai Mirai no Mi and accepts to send the future Straw Hats back to their time. Each crew member says goodbye to each other, but the future Straw Hats knew not to say anything that could influence their future. And so the crew went back to their time.
Hopefully this can provide some ending. If anyone has any questions feel free to PM me and I can answer them–I still get notifications for this account so I'll be able to answer. If anyone wants to continue/adopt this feel free to.
Thank you guys for all the support you've given (and the patience), goodbye.
