<SONG_DETAILS> [TITLE: Vaults of Unending War] [GENRE: Militarized dark ambient, industrial cinematic underscore, grimdark logistical atmosphere] [STYLE: Immersive background music for an Imperial Armoury World covered in ammunition vaults, armored depots, missile silos, proving grounds, military railways, loading gantries, weapons stockpiles, and endless preparation for distant wars] [MOOD: Disciplined, severe, watchful, oppressive, methodical, militaristic, restrained, ominous] [INSTRUMENTATION: Low industrial drones, distant marching drums, metallic loading impacts, shell-casing percussion, rail-yard resonance, heavy transport engines, hydraulic lifts, muted brass signals, restrained snare patterns, deep synth bass, bunker ventilation, warning tones, and distant weapons testing] [ARRANGEMENT: Begin with cavernous bunker ambience, low ventilation drones, and distant rail movement; introduce measured metallic impacts and restrained military percussion suggesting supply crews working in synchronized shifts; gradually add low brass signals, heavy vehicle engines, ammunition-loading machinery, and distant artillery tests; maintain a controlled sense of readiness rather than active battle; conclude with sealed blast doors, fading transport noise, and the persistent hum of guarded weapons vaults] [RHYTHM: Slow, rigid, and regimented; measured marching pulses, loading-cycle rhythms, and mechanical repetition without becoming energetic or triumphant] [MELODY: Sparse martial motifs in low brass and minor-key synth tones, deliberately incomplete and emotionally restrained] [ATMOSPHERE: Endless bunker corridors, stacked artillery shells, armored trains, guarded silos, floodlit storage yards, weapons inspectors, servitor loading crews, distant test detonations, and starships waiting to receive their cargo] [PRODUCTION: Wide cinematic industrial ambience, deep bunker reverberation, heavy low-frequency machinery, restrained percussion, subtle military sound design, seamless progression, suitable for extended tabletop roleplaying] [VOCALS: Instrumental only; no singing, choir, chanting, commands, radio dialogue, narration, spoken words, whispers, or vocal samples] [AVOID: Heroic military marches, triumphant brass fanfares, fast combat music, action trailer scoring, power metal, energetic industrial beats, modern warfare soundtrack clichés, constant explosions, or uplifting resolution] </SONG_DETAILS>
