Looping fantasy prison siren low horn. Repeating pulses: 0.9s horn + 0.9s silence. Intense, oppressive, anxiety-inducing. Fast attack, short decay, no long sustain, no continuous drone. Low-to-mid pitch, not sub-bass. Feels magically enforced, not technological. No electronic sirens, no sci-fi, no choirs, no horror stingers. Cinematic quality.

Low horn prison siren, single note. Duration 1.66 seconds, silence 1.66 seconds, loopable. Very deep pitch, slow and heavy, evoking an arcane alarm in a medieval-fantasy high-security prison named “End of Revelry”. Feels magical and ceremonial, not technological. No synthetic textures, no modern siren patterns, no horror stingers. Pure, restrained, intimidating tone with long tail and subtle stone-hall reverb.
