Years after the fall of Drago and Valka's Bewilderbeast, the Riders of Berk discover rumors of a hidden dragon sanctuary beyond the known world - a place of fire, ice, and a king unlike any they've seen. Guided by an odd, blunt, and deeply feral young man named Veikur - raised in isolation among dragons and bonded with the mysterious Ereborn - they are drawn into a forgotten realm teeming with untamed magic, brutal beauty, and a thousand secrets.
Veikur is childlike, brutally honest, and shockingly agile, wielding a dragon-forged staff and a loyalty as fierce as any Alpha. As he leads the Riders through treacherous tunnels, deadly labyrinths, and a sanctuary guarded by a mighty Bewilderbeast he calls simply "King," Heather finds herself drawn to the strange, wild soul with no concept of family - until now.
But peace in the sanctuary is fragile. Shadows stir, the balance begins to shift, and the Riders must decide if they can trust the boy raised by dragons... or if he's the only one who can save them all.
