Arthur’s kingdom
As King of Atlantis, Arthur is not just the leader there, he’s the leader of all the nations of the sea. There’s Atlantis, Xebel, Fishermen, Brine, Trench, Deserters, and a lost seventh kingdom that no one knows what happened to.
And while Arthur is clearly now the ruler of all these places, they too each have rulers who, we’d imagine, aren’t all happy this outsider has now come to their world.
