Space and Time dungeon

An old man is reborn as a Dungeon Core in another world, where he must strengthen his Dungeon and create entire worlds to prevent the invaders from reaching the Control Room. A human emperor of the new world, who feels a deep hatred towards the Dungeons and their admirers, the Scalari, because of his childhood. A young Scalari who is born in the old man's dungeon and grows up there. His dream is to explore it and meet the apostle Mephisto, the Core, in person. -- this is my first self-written story, so the characters, for example, will certainly not be perfectly fleshed out. And maybe the story is not completely "round". But I will try to get a little better with each chapter! Sorry for the info dumb in the first few chapters. I tried to get away from it quickly though. I'd love it if you guys would give the novel a chance and help me improve it.
