A place that was not twice

Elf Mauros early lost his parents and fell on the upbringing of relatives, and then troubles poured on the head of the unfortunate, like from a cornucopia. He considered himself the most unlucky elf in the world, but the truth, which accidentally discovered him in the magic iron book, turned out to be much worse: Mauros was destined to become a black marshal and conquer the whole world in the name of the god of Armars and the Dark Coalition.
The elf realized that he was a pawn in the game of the great overlords of the elements, great witches, sorcerers, gods, free spirits and even restless dead, but at the same time thousands of lives on the southern continent and the outcome of the coming war depend on it.
Will Mauros be able to get out of the brutal game of true masters of the world? Will he preserve the soul and body? Will the prophecy of the iron book come true?
