Old Chaos is the scorched cavern beneath Eleum Loyce in Dark Souls 2's Crown of the Ivory King DLC, released by FromSoftware in 2014. Players ride a lift down into the ash-filled dark to face the Burnt Ivory King, and this entrance cue marks that descent. Clips of the area's oppressive atmosphere circulated in lore videos and no-hit run compilations, where the sound became shorthand for impending doom. It endures because Souls fans instantly recognise that sinking feeling of dropping into one of the series' bleakest arenas.
