The main reason is still the difference in beliefs of the Fury Tide Kingdom.
The Lord of the Storm advocates for violence and plundering everything, destroying all enemies, while the Father of the Oak emphasizes balance and the natural cycle.
The two are inherently in conflict in their doctrines, and the way the two nations conduct themselves is also entirely different.
The Druids consider the natural environment in everything they do, even controlling their diet strictly, to avoid excessive plunder that would harm the forest.
The Fury Tide Kingdom takes whatever they can get, even regularly summoning tsunamis to capture all the fish in one swoop, throwing them onto the shore for easy harvest.
This practice has led to the extinction of several coastal fish species, which the Druids have openly condemned.
Of course, the Fury Tide Kingdom doesn't care about such things; if the fish species go extinct, so be it—it doesn't concern them.
