Perhaps the pieces of Earth will become dragon caves for the Inruusians! One metal can enthrone any provincial baron to the throne of a kingdom, who can get to an Earth city or village, rob it and go back. And then there is glass, of which ninety percent of the world is given out only by wizards. And then there's the cloth, with which the stores in the metropolis are stocked. And so much more.
Because of the transfers, Inruus is inhabited not only by humans, but also by many races that I only know about from books. Orcs and elves, trolls (not the ones that like to mock or show their malice and incompetence on the internet), goblins, lamia, centaurs and many others known only here.
Also worth mentioning about the wars.
On Inruus, everyone is at war and always has been!
The Hundred Years War, in which on Earth had marked several generations of people from almost all of Europe (although it was based on a conflict of only two countries - England and France), and the Thirty Years War, which affected the whole of Europe, is not even close. Even one kingdom is at war, spitting on the decrees of the kings, and the two empires that approach the Waste Land, there is non-stop carnage, even though both empires are at war with each other. Perhaps I shouldn't have mentioned the Hundred Years' War. In this world wars are low-key, mostly skirmishes between squads and small armies. Thousands of troops with mages are rare, and the battle is mostly scheduled in advance, even the place and time is chosen.
It's rather a bit like the Civil War in Russia, when detachments of Red, White and Green and other gray-brown and crimson types alternately captured towns and villages, then putting a black flag over the village council (or whatever the main building was called), then a red banner. But without the colossal casualties for which the fratricidal war in my country is so famous.
What else they were able to squeeze out of the prisoners... we should not live here better.
It's dangerous.
Not only are the creatures of the Void Realm plentiful, but even the shifting of blobs could cast a poisonous cloud over the main square, or send a demon and his retinue straight to the town hall. Besides, no one knows the cycles. The village can stand and five centuries, or be uprooted and thrown into another world in a year, and in its place some underwater city of intelligent amphibians (precedents described in the old chronicles).
It seems to have learned enough, but not so much. On the way to a normal understanding was a language barrier. How to solve it, we learned only a few days later.
