A dungeon core overlooked by the world. Not a reincarnation, no innate knowledge of the world; little more than a magical rock following its own path. Time will pass, and it will struggle, but as an immortal megastructure isolated from its own consequances, it will develop in unique ways. The system and everything right with the world will complain, but they will be ignored as the dungeon evolves horrors that haunt every zoologist’s dreams in its quest for strength. So welcome to the story of a dungeon and the ecological mistakes it inflicts upon the world. The Core isn't a god, it will struggle to learn as it rises from nothing. It will mess up and experience setbacks, but like a child, it will learn. Those setbacks just happen to be the ecological disaster of introducing invasive species into the world.
