Sam and Nali appeared in the Tundra realm that very night.
The place is not actually the best of the places to do business or any other development. If compared to the modern earth, this realm is the Antarctica of this whole world. Not in terms of location, but in terms of environment and atmosphere.
People even surviving and living here is actually a surprise.
But the main reason is that most people who live here are not humans, in fact, the human population that is present doesn't even belong to this realm and comes from the nearby realms which conduct some business here.
For Sam, this realm is a complete wasteland that has no use for him. Except for the frost essences and some rare herbs that grow in this type of cold and some rare beasts, there was nothing much here. Even if it is present with many rare minerals, it is almost next to impossible to mine them out.
