Advances in the world would mainly be focused on transportation. Dirigibles and submarines would be more common. Subsequently, the use of a few dials would also be a thing. Some locations, school as prisons and bases would be changed while everything else will mostly stay the same.

Since you mentioned that dials would be a thing I take it the concept of sky islands are now a common thing? As i remember sky islander's were not a common thing in the era Luffy and co existed. Also I was wondering what "Schools as Prisons" indicate, it's a specific enough phrasing that I take it this is a specific idea. 

As for location will we be visiting established areas in the canon and if so will they have changed? 

Also in terms of arc, since you mentioned initial arc I have to ask if we're starting already as a group or as individuals that will become a group?
