The Final Keeper: An OP MC Fantasy Isekai Adventure (Retrogression Keeper Book 3)

The rescue of his Party member could lead to something even more significant…

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.
