Secrets of Berk And Arcadia

Years after dragons vanished into the Hidden World and Arcadia survived the rise of ancient magic, Jim Lake Jr. still bears the Amulet of Daylight as the true Trollhunter. But Jim carries something else, too-a memory of a future that never was. A fractured vision of loss. Of sacrifice. Of a world undone by a single choice.
He refuses to let it become reality.
When a violent surge of primordial energy shakes both Berk and Trollmarket, an ancient name resurfaces-one deliberately erased from history.
Vaelrath the Severed.
A being born of two realms.
Sealed away before dragons and trolls ever stood united.
A force that believes connection itself is the flaw in the world.
As the barriers between Berk and Arcadia begin to weaken, Hiccup Haddock faces a choice he once thought final-whether dragons should remain hidden... or return to a world that may not deserve them. When Toothless answers a call older than memory, the past and present collide. With Astrid and Claire at their sides, and the weight of destiny pressing in once more, Jim and Hiccup must lead together-this time not because they were chosen, but because they choose to stand. Jim has already seen what happens when unity fails. And he will not let history repeat itself. Because some secrets were buried for a reason. And some villains cannot be redeemed.
