Plague Nun in Haunted Infirmary

Prompt:

Imposing plague nun in abandoned stone infirmary cloaked in creeping fog, bleached habit stained with crimson, hollow eyes peering beneath a carved wooden mask, soft candlelight and deep chiaroscuro casting long shadows, velvet rot and tarnished gilt, fractured mirrors multiplying her poise, ornate filigree curling like serpents, whispering curtains and drifting dust suggest absent crowds, surreal intrusions (levitating frames, warped reflections, clock hands reversed), painterly brushwork, muted golds and bruised blues with wine-red accents, opulence and menace entwined, time paused between aria and collapse.
