The Möbius Dual-World Mage [Cyberpunk | Portal | Progression]

180,000 Terra Credits in debt. Three days before the Abyssal Mines claim him. In the cyber-wasteland of the Terra Republic, mana is not a gift of nature—it is a resource monopolized by megacorporations. For those at the bottom, even the faintest magical opportunity comes with a price. Rowan Vance is one of them. During a brutal Republic Military recruitment exam, the strange Möbius Ring birthmark on his wrist activates, tearing open a spatial rift and throwing him into another world—a wild realm of abundant mana, natural resources, and deadly Mana-Beasts. But this new world is not a treasure chest. Its wilderness is dangerous, its magic is unfamiliar, and every gain must be earned through risk. Rowan’s greatest advantage is the gap between two civilizations. With Terra’s hard magic, magitech arrays, and engineering models, he begins hunting Mana-Beasts, smuggling resources, refining spells, buying equipment, and clawing his way out of debt one dangerous trip at a time. The corporations are watching. The military exam is approaching. And every shortcut between worlds comes with a cost. What to Expect: Weak-to-Strong Progression: Gritty, earned power-ups.
