Chapter 5 - The Vanguard's Doom

The imperial vanguard, led by General Vaneh—a ruthless commander known as the Butcher of the East—surged around the final bend of the mountain pass, expecting to find a demoralized garrison guarding rusted and broken gates. Instead, they found themselves staring down the throat of an awakened titan.
The valley floor trembled as the ancient defensive earthworks shifted. Hidden drawbridges, operated by Margaret’s meticulous adjustments to the hydraulic manifolds miles away, suddenly retracted, plunging the front ranks of the imperial cavalry into deep, dry moats lined with razor-sharp slate spikes.
"Halt! Halt the advance!" General Vaneh screamed, reigning his foaming warhorse to a violent stop as he stared up at the blazing heights of Fortress Kaelen.
The azure fire blazing along the ramparts was not mere flame; it was a concentrated thermal grid, managed from the central chamber by Clara, who sat before an illuminated slate table covered in glowing calculus calculations. With every flick of her pen, targeting vectors adjusted with pinpoint mathematical precision.
"Range to enemy siege engines: twelve hundred yards," Clara stated calmly, her voice steady as a surgeon's blade. "Wind shear from the eastern ridge: four knots south-southeast. Adjusting trajectory by point four degrees."
Beside her, Margaret pulled down a massive brass lever.
High above the valley, heavy stone-throwers—not built of wood and rope, but forged from solid counter-weighted bedrock—swiveled with terrifying speed. They released massive blocks of granite that whistled through the air like falling stars, crashing directly into the center of the imperial siege train with apocalyptic force. Splintered wood, shattered iron, and pulverized stone erupted in a series of colossal shockwaves that decimated the enemy vanguard in seconds.
Down in the courtyard, Lord William and his officers watched in stunned silence. The mighty imperial army, which had conquered three kingdoms in a single season, was being systematically dismantled not by swords or shields, but by pure, unadulterated engineering genius.
"They're... they're wiping them out," whispered one of William’s senior captains, dropping his sword point to the dirt. "Without a single infantry charge."
Rose, having descended from the signal tower with effortless agility, landed softly on the stone flags beside her mother and sisters, wiping a smudge of soot from her cheek with a grin. "Well, the eastern wing is clear," she announced brightly. "Though the cavalry regiment trying to sneak around the western ravine looks like they need a proper welcoming committee."
Anne looked down at her youngest daughter with a faint, affectionate smile. "Go give them one, Rose."
"With pleasure," Rose laughed, darting off toward the hidden postern tunnel with the speed of an arrow released from a master bow.

General Vaneh, realizing his glorious invasion had turned into an absolute slaughterhouse, tried to sound a retreat. But it was already too late. Clara had locked down the pass coordinates. The mountain gates slammed shut behind the retreating imperial columns, trapping them in a crushing vise between the impassable rock faces and the overwhelming artillery of the three Sentinels.
By midday, the battle was over. The great Vaelen host had broken apart like glass against a diamond anvil.
