THE MORNING AFTER GRANDPA'S FUNERAL, MY PARENTS CAME TO STEAL HIS HOUSE. THEY NEVER EXPECTED THE MAN WAITING BEHIND HIS STUDY DOOR

The world disintegrated into blinding white thunder.

Arthur hadn’t wired the ceiling; he had wired the rusted support struts beneath the catwalk itself. The steel platform dropped four feet with an ear-splitting shriek of shearing rivets. The FBI tactical team lost their footing instantly, weapons discharging into the cavern ceiling in a frantic chorus of deafening ricochets.

The blast wave threw me forward. My shoulder smashed violently into the cold titanium slab. Instinctively, my hands shot out to brace for the impact.

My right palm slammed directly against the brass plate.

A violent, electric hum vibrated through the metal. A lattice of emerald laser lines swept across my skin, analyzing ridges, sweat pores, and dermal capillaries at the speed of light. From deep within the stone housing, hydraulic pumps roared to life with the sound of a submerged submarine blowing its ballast tanks.

*BIOMETRIC CONFIRMATION: VANCE, GENERAL JAMES (DESCENDANT ALPHA). CLEARANCE GRANTED.*

The automated voice was flat, synthesized in an era before modern digital speech, carrying the mechanical cadence of the late Cold War. The six-inch-thick vault door did not swing; it split vertically down the middle, retreating into the bedrock with a deafening hiss of pressurized nitrogen.

"Mark! Get inside!" Arthur bellowed.

He was on his knees, his face streaked with soot and blood where shrapnel had grazed his temple. Through the smoke, Sterling Vance was already recovering, drawing a nickel-plated automatic from his tailored holster.

"Secure the terminal!" Sterling shouted over the roar of the machinery. "Kill the carpenter! Bring me the boy's arm!"

Submachine gun fire chewed through the air, carving chunks of stone from the doorway. Arthur lunged forward, catching me by the collar and shoving me violently through the threshold into the pitch-black abyss beyond. He rolled in after me, hitting an emergency manual override recessed into the interior bulkhead.

The dual titanium slabs slammed shut with the finality of a tomb.

The immediate silence was suffocating. Outside, the muffled thud of bullets against the exterior armor sounded like harmless rain against a metal roof.

"Arthur?" I gasped in the dark, my hand shaking violently. "Arthur, are you hit?"

A match flared. Arthur’s face appeared in the tiny sphere of yellow light, his breathing shallow, a dark stain spreading across the wool overcoat just beneath his collarbone.

"I've been hit worse by better men," he rasped, coughing until crimson flecks dotted his lip. He reached out with trembling fingers and found a master breaker switch on the wall. "Welcome to Archangel, kid. Grandpa’s real workshop."
