Immediately as Shin entered the metal fortress, his ears were greeted by the clanging of metal and the rhythmic sound of drills, mingling with the distant thud of artillery testing and the sharp bark of orders.
The structure itself loomed large, an intimidating monolith of steel and concrete, its exterior marked by the relentless pace of military efficiency.
The air inside was filled with the tang of oil and metal, punctuated by the whirring of machines and the distant rumble of tanks rolling across the yard.
The interior was a hive of activity: protectors in uniform moved with purpose, their boots echoing on the polished floors.
Offices lined the long corridors, each door marked with the rank and title of the occupants within.
The walls were bare, save for the occasional motivational poster or a map detailing current or past sea subjugation operations.
