She is the shadowy third sister of the ZORYI. According to some sources, she is a nameless third goddess who looks after the night while her sisters mark the dawn and dusk.
Celebrated writer and genius NEIL GAIMAN, who included the ZORYI in his superlative novel American Gods, bestowed upon her the name ZORYA-POLUNOCHNAYA (‘Midnight Star’).
However, despite some reports to the contrary, he did not actually invent her. He did, however, do wonderful things for her self-esteem.
