Madame of Roma
- "Madonna Solari pushes us to mingle. Flirt. Romance. Seduce. Whatever necessary."
- ―Fiora Cavazza describing her Madame, 1497.[src]
As the owner of the popular Rosa in Fiore, Madonna Solari encouraged her courtesans to do "whatever necessary" in order to gain their visitors' patronage. Despite playing host to many customers, the brothel itself was not in good shape, and as Fiora Cavazza once described, "Filth can be hidden by shadows. Foul smells masked by stronger scents, mostly imported. Disease is... difficult."
Solari would also quickly dismiss any of her girls who showed symptoms of disease, but as they entertained many clients from several foreign lands, they were fighting a losing battle. At one point, Madonna Solari and her brother attempted to delve into slave trade as well; however, this angered Cesare Borgia, who saw this as "dabbling in trades where they [were] unwelcome." In exchange for their lives, she and Santino allowed Cesare to take one of their courtesans as his own, to which he chose Fiora Cavazza.
For a time, Madonna Solari aided the Assassins in their fight against the Borgia, but soon became lazy, taking preference to attending parties instead. She also began taking bribes from Templar priests and clergymen to divulge information about the Assassins.
In 1500, Madonna Solari was taken captive by Cento Occhi slave traders under the order of Cesare Borgia, who promised to release her for 2,500 florins. Ezio Auditore da Firenze, who had recently arrived in Rome, gathered the money and went to the slave traders' ship. However, the slave traders did not keep their promise, and slit Madonna Solari's throat instead. Ezio's sister Claudia and her mother Maria then took over ownership of Rosa in Fiore, when the Assassin returned with news of Solari's death.
- Similar to her brother, Madonna Solari's character model was randomly generated, though she would always be shown as a courtesan.
- Her surname, Solari, is a family name derived from Latin word solarium, literally "a place in the sun". Madonna is an Italian honorific, meaning 'my lady'.
