In the rugged, unforgiving landscape of late 12th-century Scotland, a secret is born in blood and sorrow. Within the stone walls of the MacKenzie holding, Margaret MacKenzie, daughter of the formidable Laird Liam MacKenzie, gives birth to identical twin sons. The joy of their arrival is tragically cut short as Margaret perishes, leaving her sons motherless. Laird Liam, his heart heavy with grief, cradles his grandsons and makes a solemn vow. He conceals the most dangerous truth in all of Scotland. The throne of Scotland is occupied by the self-proclaimed King Bartholomew Kilgore, a man who clawed his way to power through the murder of his own cousin, King Malcolm. Though he wears the crown. His paranoia leads him to scour the castle for any lingering threats. He uncovers a brittle marriage scroll, irrefutable proof that King Malcolm had a first wife, Margaret MacKenzie. The existence of twin sons whose claim to the throne eclipses his own. He unleashes his forces upon their holding in a merciless midnight raid. Drawn by rumors of the impending attack, the four most feared warriors of the north—Lairds Nikolaz MacCallum, Killian Kincaid, Broc Buchanan, and Kai Sinclair—ride with the force of a Highland storm. They arrive too late to prevent the slaughter but just in time for retribution. In the chaos of the massacre and its aftermath, the nine-year-old twins, William and Wyatt, along with their young friend Grant Sinclair, escape through a secret passage, vanishing into the night. Believing the boys to have perished in the flames and bloodshed, the Lairds depart with heavy hearts, convinced that Scotland’s rightful heirs are lost forever. A different kind of fire forges a warrior in the Highlands they left behind. The peaceful village of Raven Hollow is razed to the ground, leaving a young boy named Gareth MacBrayne an orphan. This crucible of loss hardens him into the formidable mercenary known only as "Angus Forest," a man driven by a relentless quest for vengeance and a desperate search for his lost sister, his destiny unknowingly interwoven with the fate of the hidden princes. Fifteen years later, William and Wyatt MacKenzie return to Scotland. No longer boys, but men trained in the arts of war and diplomacy, they are ready to reclaim their ancestral home and birthright. The legacy of betrayal that defined their childhood is reborn, but this time, the threat comes from within. In the shadows, Wyatt has sought the aid of Bhaltar Kilgore, the son of the very tyrant who murdered their family, unaware that the tyrant’s son has his own dark ambitions for the Scottish throne. As brother prepares to turn against brother, a new and more personal conflict is set to engulf the Highlands, promising a storm of blood and betrayal that will dwarf all that has come before. An attack of such brutality does not go unnoticed in the Highlands. From the highest peaks, three beacons were lit, their flames cutting through the darkness, a desperate cry for aid that was answered with terrifying speed. The signal summoned the four Lairds of the north. This is not merely a tale of survival, but a saga woven from the threads of destiny. The conflict is deeper than clan feuds, rooted in ancient prophecies, hidden lineage, and betrayals that echo across generations. A mysterious bard named Angus, whose whimsical tunes and playful exterior mask the instincts of a ruthless killer, emerges from the shadows. Sent on a mission that put him on the children's trail, he finds himself their unlikely protector, his own quest for vengeance now intertwined with the fate of the innocents. His path is bound to secrets buried in the past, secrets now coming to light through parchments written in an ancient tongue and intricate Celtic.
