Matthias was born into a wealthy family in Prague. His father, a descendant of a fallen ancient clan, possessed god-like puppetry skills that provided a comfortable income.

The family gained explosive fame through performances in Paris. As wealth and fame flowed in, his father became an artist and his socially active mother became a renowned noblewoman.

As Florian grew up, he heard many voices of pity—sympathy for his parents who desperately protected him from the flames in that fire accident, and for Florian's fate of losing his parents and entering an orphanage. Every time the orphanage director told Florian's story to donors, everyone was moved by this selfless love and praised the miracle of life. While he inherited the miracle of love, Florian spent countless nights in the dream of that day—the sight of his parents left behind in the room being swallowed by flames played repeatedly in his mind. Florian began to believe the adults' stories, thinking that although his parents vanished in the fire, their love is still right beside him. Thinking this way eased the pain of bereavement, and the haunting nightmares, while painful, became a sort of guidance or revelation.
