About the film

A kingdom lost. A bloodline hunted. A destiny awakened. PREMISE: Fifteen years after a warlord-sorcerer slayed the High King and seized the throne of Roncalion, the king’s four heirs, hidden and scattered across the realm, must reunite to reclaim their legacy. Led by Gryff, the eldest heir, and armed with four magical gemstones, they embark on a perilous quest to overthrow the usurper king, unite a fractured kingdom, and confront the greatest obstacle of all: themselves. FUN FACT: This is all based on a bedtime story our dad told us when we were kids. We've since reimagined it as our own, and turned it into an epic fantasy novel trilogy, which we're eager to share with you all. We're nearly finished with the first book in the series. If you think the trailer is cool, you'll love the actual book. Directed by Morgan Rosenblum. Written and Created by the Rosenblum Brothers (Morgan Rosenblum and Owen Rosenblum).
