The Rose Beneath the Opera

In a crumbling kingdom swallowed by endless winter, an abandoned opera house stands hidden beneath the cliffs outside the capital city. Once magnificent, it has become a place of rumors:
They say a beast lives below the stage.
They say music echoes through the tunnels at night.
They say no one who sees his face ever speaks of it again.
When Belle Laurent's father disappears after seeking shelter in the forbidden opera house during a storm, Belle ventures inside to rescue him.
Instead, she discovers him.
Not entirely beast. Not entirely man.
A masked composer cursed long ago for an act of cruelty and pride.
