[@FallenTrinity]I hinted a bit into where the story is in the setting section, but to be more precise one of the biggest changes would be dial based weapons and wapometal tech, which are both canon to the story. I'm leaving it up to y'all to really decide what you want to do with the tech.

Something like a personalized vehicle that can be land or seafaring is fairly common, like a powerful speedboat or sailboard. I've also mentioned that airships and submarines are not that rare, but kind of exclusive. Transforming ships are fine too so having a character who uses some kind of "transforming" armor isn't Feel free to make use of the "transforming weapons" aspect i mentioned above, it won't be anything severe, but for fans of the RWBY series, having a weapon have multiple functions, someone suddenly whipping out a giant hammer, or turning small metal orbs into spears, is something that i will allow and wholly entertain. I will also be fairly flexible in allowing weapons with elemental add ons or some fairly unique aspects by way of using Dial tech or maybe they have a weapon that was infused with a devil fruit (more on this later), granted there will be limitations, but i'm open enough to the idea.
