It is 1870: in the Royal Opera House in the freezing city of C-, a chandelier shaped like a galleon sparkles with the light of 750 candles in memory of a vessel and its passengers, who vanished without a trace.

Here they must tread softly in the Cave of Dreamers, face the man in the emerald green suit and play a terrifying game called the Reckoning to save those they love.
