The ads enthused, "The virtual lands of Mirror World await you! Live out your most secret dreams in our world of Sword and Sorcery! Become a Great Wizard or a Famous Warrior! Build your own castle, tame a dragon, conquer a kingdom! All those desperate, lonely, and insecure - Mirror World offers you a chance!" But Oleg isn't meant to become a great wizard or a famous warrior. He'll never have a castle of his own. Nor will he ever tame a dragon. And he's definitely not the type to conquer a kingdom, however virtual it may be.

Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since. None of this mattered much to Derek, aside from making living a little more perilous.

Eric was born in a world governed by the Great System, in the family of Aren Bergman, a respected miner from Orchus. But the joy of gaining a son was overshadowed by the newborn's terrible affliction. Eric was completely nulled-level zero and no characteristics points. The only things keeping him from dying were his tiny base supplies of "life" and "energy". The medicine woman who delivered Eric believes this to be the work of the evil spirit, Bug. Due to the peculiar laws of the Great System, Eric cannot use experience essences or characteristics tablets.

Matt plans to delve the rifts responsible for the monsters that destroyed his city and murdered his parents. But his dreams are crushed when his Tier 1 Talent is rated as detrimental and no guild or group will take him. Working at a nearby inn, he meets a mysterious and powerful couple. They give him a chance to join the Path of Ascension, an empire-wide race to ascend the Tiers and become living legends. With their recommendation and a stolen Skill, Matt begins his journey to the peak of power. Maybe then, he can get vengeance he seeks.

Life’s tough when you’re trapped in an eight-year-old body on another world. His name is Eight. Not really, but that’s what the System decided after a slip of the tongue. One moment, he was stepping out the office door on the way home, and the next waking up on a hillside below a town wall. Oh, and the gate guard drove him off, because he thought Eight was a monster. What’s a boy to do in a world full of magic and so many, many hungry creatures searching for their next meal? Well, there’s an old man inside that body, and he'll use everything he’s learned to survive.
