From the Succubus Archduke to the Human Lord

This is a world of swords and magic, but it's not what you think. Gods walk on the earth, but they are not supreme. Each god coexists with a world, in which they are omnipotent, but are also subject to the rules of the world itself - those who kill indiscriminately will be abandoned by the world, and devouring the territories of other gods is their way to become stronger. The devil is the most greedy predator among them. Relics are everywhere, but they are not gifts from the gods. The sacred tree of the elves, the mountain hearth furnace of the dwarves, the ley lines of the human royal city... These miracles that are regarded as sources of power by various races are actually the remains of a long-extinct human civilization that once conducted interstellar voyages. They are still operating silently, maintaining the fragile balance of the world, and also hiding the truth about the self-destruction of the old civilization. The continent is isolated by an invisible wall, but it is not naturally formed. The surrounding destructive storm and deep-sea restricted area are the ultimate test and protection procedures left by the old civilization. The continent itself is a huge "Noah's Ark" built by ancient machinery. This is a carefully designed stage. The glory and despair of the ancient times are sealed in the ruins. The walking gods play in the chess game of the rules of heaven and earth, while the mortal races - humans, orcs, elves, and demons - repeat the cycle of hatred and war in ignorance. Until someone started reading the "instructions" of the ruins and tried to rewrite the "underlying code" of this world.
