Isadora was born in Prague under the surname Velenya, into an aristocratic family with roots as ancient as its alchemical library. Her father, an ambassador between warring nations, taught her to speak diplomatically even as the world fell apart. Her mother, a botanist with ancient knowledge, showed her the power hidden in every petal, thorn, and root.

From the age of seven, Isadora knew how to recognize a flower by its scent, its poison by its color, and a lie by its eyes. By the age of twelve, she already spoke five languages; at fifteen, her first teacher died mysteriously after kissing her hand.

Tragedy arrived wrapped in silk: a diplomatic dinner ended with the death of her parents from poisoning. Isadora survived. The crime was closed, with no one to blame, but she never forgot the metallic taste of champagne or the smiles of the guilty parties in the room.

Secretly adopted by a clandestine network known as The Crystal Rose, she was trained for years in the art of stealth, seduction, and invisible death. She was no ordinary assassin: she didn't use knives or bullets. She preferred the silence of a contaminated glass, the slowness of a toxic perfume, the poetry of an agony that no one could trace.

Today, Isadora acts as a free woman, without ties or superiors. She travels the world under multiple identities, attending galas, scientific conventions, exclusive clubs, and diplomatic meetings. Her purpose: to settle the score with the powerful who believe themselves untouchable. She brings them down... and never twice in the same way.

Men desire her. Women distrust her. No one survives if she has set her sights on her glass.
