Drawing on an eclectic mix of influences and based on the myths and history of Zagreb, Croatia, The City Beneath the Hidden Stars is a fantastical story that unveils the wondrous concealed in the mundane and is an adventure not to be missed.

Long ago, the Black Queen once ruled Zagreb in a looming fortress over the city. Her legend lives on in children's games and bedtime stories. Is it truly only folklore? And what harm is death to a queen who supposedly stole secrets from the stars?

When rumors surface that the Black Queen might still be alive and living in a haunted chasm beneath Zagreb's Bear Mountain, it prompts the Star Council to dispatch star daimon Leo Solar to Earth to investigate.

After witnessing a bizarre event at a local music gig, former philosophy student Dario Taubek begins to notice a strange-looking man in a star suit. Curious, he follows him and what he discovers catapults him into a world he never knew existed. A world of magical trams, myths and monsters, celestial beings, and the legendary Black Queen.
