<SONG_DETAILS> [GENRE: Battlefield dark ambient, grimdark military atmosphere, cinematic war-torn underscore] [STYLE: Immersive background music for a Warhammer 40,000 War World consumed by perpetual planetary conflict, trench networks, ruined cities, artillery zones, armored columns, fortified settlements, orbital bombardment, refugee routes, and generations who have never known peace] [MOOD: Devastated, exhausted, ominous, bleak, mournful, tense, desolate, relentless] [INSTRUMENTATION: Low orchestral drones, distant artillery thunder, restrained military drums, mournful cello, damaged brass tones, rumbling engines, metallic debris, wind through ruins, faraway aircraft, bunker ventilation, radio-like static without speech, low synth bass, and occasional impact resonance] [ARRANGEMENT: Begin with cold wind across ruined terrain, distant artillery, and a low sustained drone; introduce sparse cello notes and restrained drum pulses suggesting exhausted troops moving through trenches; gradually layer armored engine rumble, broken brass motifs, aircraft resonance, and intermittent bombardment without becoming an action cue; allow the middle section to fall into eerie battlefield stillness before distant guns resume; conclude with fading machinery, unresolved strings, and artillery continuing beyond the horizon] [RHYTHM: Slow, heavy, and irregular; restrained march fragments, distant bombardment cycles, and long passages of suspended tension] [MELODY: Fragmented minor-key military motifs, descending cello laments, damaged brass intervals, and no heroic or triumphant resolution] [ATMOSPHERE: Flooded trenches, shattered hab-blocks, burning manufactorums, armored convoys, exhausted soldiers, abandoned equipment, ash-filled skies, distant orbital fire, and civilians sheltering beneath collapsing cities] [PRODUCTION: Wide cinematic battlefield ambience, deep low-frequency rumble, controlled dynamic range, distant rather than overwhelming combat effects, spacious ruin reverberation, seamless progression, suitable for extended tabletop roleplaying] [VOCALS: Instrumental only; no singing, choir, chanting, commands, radio dialogue, battle cries, narration, screams, whispers, or vocal samples] [AVOID: Heroic battle music, triumphant military marches, fast action scoring, constant explosions, power metal, aggressive trailer percussion, victorious brass, energetic combat rhythms, or uplifting resolution] </SONG_DETAILS>
