So, I was looking back at Chapter 1,076 and I noticed the buildings around Elbaf do reflect the architecture of Viking Age Scandinavia well enough....but are relatively primitive by the standards of other places across the world. Also, as old legends in Dorry and Brogy, return, I think I might have deduced the root of conflict for the arc.
I think whoever the villain is will want to "modernize" Elbaf, taking it away from it's Viking roots and even seek to join the World Government, adopting their rules and customs, an analogy of how the Christianization of Scandinavia took it from decentralized petty kings and jarls to a unified, stable country, the foundations of modern Denmark, Sweden, etc. And old traditions like the Giant Warrior Pirates have to go. For their part, there's no way the World Government would miss a chance to bring Elbaf under their control, even if it means making giant-sized ships and weapons for the villain's modernized army.
So, it will be a conflict of tradition versus modernization, I believe.
