In a cavernous, crumbling vault, the sound of grinding gears broke the silence. A vault door, encrusted with layers of rust and grime, groaned open as a surge of pale blue light spilled into the chamber. Inside, amidst rows of shattered stasis pods, one remained intact. Within it, a sleek humanoid form lay dormant, its chassis crafted of blackened alloy laced with veins of glowing circuitry. The inscriptions on the pod, written in a language lost to time, read:

"Unit 7-19-ALPHA. Designation: Apex Sentinel. Priority Directive: Protect Humanity."

A low hum grew louder as the stasis pod’s systems activated, and with a hiss of pressurized air, the glass casing slid open. The machine's optics flickered to life—twin orbs of brilliant white light. Its sensors activated in rapid succession, scanning the area.

"Time elapsed: 23,847 years. Environment compromised. No signs of human civilization detected. Anomalous lifeforms present. Initiating observation.” After a few seconds it already understood the battlefield. “Subjects: Xenos. Designation: Orks. Analysis: Hostile, non-human aggressors. Threat level: High. Course of action: Eliminate."

The Men of Iron—Apex Sentinel—rose from the pod, its movements fluid yet purposeful. Its towering frame exuded an aura of cold efficiency, the pinnacle of ancient human ingenuity. The Orks noticed the sudden collapse of the building and the figure standing atop it. One of them—a hulking Warboss clad in rusted armor—pointed with a massive claw.

“Oi! Wot’s dat shiny git doin’ up dere? Looks fancy, boys! Let’s krump it!”

The Warboss fired his gun, a cobbled-together monstrosity of mismatched parts, sending a hail of explosive rounds toward the Sentinel. The rounds detonated harmlessly against its energy shield. The Sentinel's gaze fixed on the Warboss, calculating his size, weight, and movement patterns.

"Crude. Primitive. Yet... persistent. Their kind should not thrive, yet they do."
