Revianor was born to an affluent merchantman and his wife in the port city of Pelargir, their second child and only daughter.  Revianor's parents are Dunedain of the South, having the blood of Numenorean Sailors coursing in their veins, though how pure their blood would be is unknown.  She is seven years junior to her brother, the family's firstborn son Varyandil, upon whom the parents spent a great deal of their wealth and influence in preparing for a life of glory and honor as a knight of Gondor.  Her parents had hoped for a second son, and while disappointed in the fact she wasn't male, they did show her love and compassion raising her.

While Varyandil was raised to be the pride of the family, Revianor was raised to be educated yet womanly, learning the histories of Gondor and stories of Numenor so that she would one day pass the stories to her own children, while simultaneously being taught etiquette, manners, and housework.  Revianor viewed this as her family wishing to marry her off to a life of housewife while her brother earned the family pomp and pride, and as such she took any time off she could speaking with the many sailors and merchants in Pelargir.  She yearned for the sea, to relive the stories of the Ship Kings that made Pelargir a great harborage, or the great Sailors of Numenor charting the unknown shores of Middle-Earth.  With her brother's help, she eventually came to own a small run-down trade ship that she spent two years repairing on with her own time and energy.

In time she had a small ship and a small crew, and while her parents were not enthused they each gifted her for her maiden voyage: Her father gave her his old chainmail hauberk and longcoat, while her mother hand-crafted a long shawl for her to keep warm on the seas.  From then on, Revianor sailed the Ethir Anduin transporting goods across the local area, before eventually making trips up the Anduin and other rivers in Lebinnin, and even expanding operations to Belfalas and Anfalas.

In her first major deal she was offered a moderate sum of coin to sail around Andrast and up the coast to the river Gwathlo, transporting goods to Tharbad on behalf of another captain visiting Pelargir.  A storm knocked the crew off course before grounding the ship on the coast of Minhiriath, destroying the vessel.  Revianor awoke on the shore with a small number of her sailors, saved from being washed out to sea by an elf woman.  With no ship, no supplies, and no way home, Revianor and three survivors enlisted with the elf's small group, the Erbin i Min Dhuath, where they seek to aid the Free Peoples of Eriador and make enough coin to recoup their losses and go home.
