Rizzoti was Hemanite woman living in the 24th century.
She spent the majority of her life as a diplomat in the State Department of the United Federation of Planets.
While there she managed to secure permission for a consulate and a medical clinic.
In 2376 she was made the Federation's Ambassador to Bajor. She and Commodore Nikolas Stone were immediately at odds due to her sending a request through Colonel Kira instead of his chain of command. He had her arrested on charges of conspiring to disrupt Starfleet operations with a member of a foreign military. The charges were dropped shortly afterward. ("Gatekeeper")
