Unfortunately, all I have are drafts – handwritten! But I can briefly outline the main idea: The book is written as a diary, initially from the perspective of a single character, a dwarf. However, as the book progresses, the dwarf sacrifices himself.
Because Alvin, once a great mage and now a Necromancer, was cursed by his brethren (who, by that time, were not as well-versed in black magic). He rises 400 years after his death, having learned the meaning of magic and remembering his past life. He creates a Golem, imbuing it with the soul not of a simple warrior, but of Gaish, the greatest and most ruthless tyrant in the history of the world (by the way, I don't know what to call this world!).
Alvin raises thousands of warriors (in short, he creates an empire called the NECROMANCERs), and joins forces with vampires, etc. So, the Golem turns out to be a Blood Titan (mages had never done this before; Titans didn't exist!). This Titan was impervious to arrows, swords, or magic. But there was a legend that somewhere in the mountains, there was a ruined tomb of the stingy dwarf, Hekin, who possessed a magical pickaxe capable of destroying anything, but in exchange for the owner's soul (if you strike with the pickaxe even once, you will become so greedy that you will go to the mountains and endlessly chip away at the walls until your strength fails you).
What did the dwarf do? But his father was a miner and rarely saw the light of day; he always wanted to know what was beyond the mountains, but never found out. His son also hadn't been beyond the mountains and decided to fulfill his father's wish to cross the mountains and record everything he saw.
Dying after one of the battles, he passes the book on to a HUMAN, and a new chapter, a new story begins, also with a war between the alliance (humans, mages, elves, dwarves) and the union of dark forces (Necromancers, Orcs (possibly Orcs will be neutral), Inferno).
That's it.
