The Final KeeperAn OP MC Fantasy Isekai Adventure
After arriving in an alternate timeline with the intention of getting his Party member, Vintrella, back from the Spirit Sentinel Faction, Bax disturbs a hornet’s nest of politics and power and he has no intention of getting involved. Unfortunately for him, the leadership behind the Faction who took Vintrella aren’t likely to let their captive go after what Bax did to one of their Elite Masters, and they hatch a plan to trap and kill the powerful Keeper once he travels to the Faction’s capital.
But Bax isn’t just some random Mercenary looking to stir up trouble. With the help of Ardriene, a local Magitech Engineer, Bax isn’t going to let anything stand in his way of getting Vintrella back from the clutches of those that would mean her harm.
What none of them realize, though, is that what starts as a relatively minor confrontation between a Faction and one individual will explode into a conflict that won’t just spread globally, but throughout the entire Retrogression System universe. With everyone other than his only friends seemingly against him, the final Keeper within both timelines will have to pull out all the stops to ensure he survives what is coming.
This story contains an overpowered main character, LitRPG progression mechanics and stats, and isekai/portal fantasy elements. Contains no sexual content or harems.

Jonathan Brooks
In the fast-evolving realm of LitRPG and Dungeon Core fiction, few names have carved out territory as boldly—or as prolifically—as Jonathan Brooks. Known for weaving complex magic systems with the logic of game mechanics, Brooks has become a touchstone for readers who crave fantasy grounded in strategy, growth, and immersive world-building.
It all began with Dungeon Player in 2017, a debut that hinted at the intricate worlds and evolving systems that would become his signature. But Brooks didn’t stop there. He’s since written more than 70 novels, building expansive series like Dungeon Crafting, Magical Fusion, and Earthen Contenders, each exploring what it means to level up—whether as a character, a dungeon, or a sentient core learning how to survive in hostile worlds. His latest venture, The Labyrinth World series, continues this evolution with a fresh spin on multiverse mechanics and layered storytelling.
