A reasonable point.
Why Exiled Land has so many cultures? How did the exiles arrive the Exiled Land?
If we look into Elden Ring’s lore, you see the similar puzzle about its Land Between and the inhabitants of the Land Between.
My theory about ER’s Land Between is, it’s a land between the world of reality(where the player character came from) and the realm of spiritual of that reality world’s cognitional creation. The place where the player character of ER first got spawned, a chapel, is similar to the tunnel in Spirited Away by Hayao Miyazaki, which connects the real world and the fantasy world.
And back to my questions, “Why Exiled Land has so many cultures? How did the exiles arrive the Exiled Land?”
My version is, the Exiled Land is actually the realm of the dead of the hybrid culture of its realm of the living counterpart, the giant kings were actually the ruler of this realm of dead as well as the god or goddess of death in the realm of the living that the people believes or once believes. The exiles, they were not exiled, but dead instead. All exiles were merely ghosts who joined in afterlife and so they arrived at Exiled Land. That’s why you met Conan, a long dead man’s ghost, whose living days had only classic-age looking kingdoms and tribes, instead of renaissance-age looking armors and ships that nowaday Exiled Land provides. That’s because in the realm of the living, kingdoms rise and fall, cultures emerge and combine, technology flow advance. Everything changed and still are changing.
In the beginning, the realm of the living of the Conan world. There was animism, then polytheism. At first, the realm of the dead was just a realm of anima that connects all, both the living and the dead. And its true rulers, Dagon, Jhebbal Sag, and Yog, then the intellectual living human created idols, and one of them rules the death. That’s the first giant king, the most hideous god of death and the most unforgiving slaver king. The living human has powerful sorcery priests, they overcame Dagon and Yog in their own realm. The first giant king rules all. All the dead, their ghost and soul were enslaved via the highway til the eternity to become a part of that now known as the Unnamed City. And then in realm of the living, new cults arise, Set, Mitra, Derketo, and Ymir.
As for Crom, he was never a ruler, he was not even a him who don’t take tribute of any kind from slaves of any kind.
The Forgotten Tribe, the people there were right about one thing, that all outsides are dead, but wrong about another, that themselves, are dead as well. The message book on a bench near the tribe’s north-east exit actually hinted this. But the rest of the Exiled Land doesn’t seem to hint the same way. Which is a pity.
