What was supposed to be a simple ride with friends becomes a descent into the unknown.

Marco and Guy are still just two passionate motorcyclists. One a mechanic ? instinctive, grounded in reality. The other an engineer ? analytical, drawn to systems and anomalies. They ride for the open road, for a freedom that needs no justification.

Until the message.

Léa, an old friend, calls them from Zagreb. Her voice is strained. She speaks of an abandoned castle, forgotten tunnels, disappearances no one can explain ? and of a name the locals refuse to say out loud: the ?trigon.

Something is wrong in the city. The streets are alive, but only on the surface. Conversations stop when certain words come up. Eyes look away. Silence settles in too fast, too often.

The deeper Marco and Guy dig, the clearer one truth becomes: this isn't a legend. It isn't a myth. It's a presence ? patient, ancient, and hungry, breathing beneath the ruins of Medvedgrad.

Landmarks vanish. Time bends. Fear takes on weight and shape.

Because the ?trigon doesn't hunt bodies. It feeds on spirits.

Blending supernatural thriller, psychological horror, and high-speed adventure, The Black Queen and the Vampire explores a fear more insidious than death itself ? the fear of losing who you are.

In a Croatia where reality is cracking at the seams, Marco and Guy will have to face something far bigger than one entity: their own limits, their memories, and everything that still ties them to the world they know.

Because in the tunnels beneath Samobor, one rule holds:

What you watch, watches you back.
