At first glance, Rosalie is no different from any other young woman of means in 1920s New York.  She would never be considered classically beautiful, but she's pretty enough to those that notice such things.  Her height (5'6") and weight (130 lbs) are both average, and her build is slender and curvy rather than toned or athletic.  Her most striking features are her vividly blue eyes and shoulder-length auburn hair, normally curled or coiffed in common fashion.  Coming from a family of modest wealth, Rosalie has always been a fashionable dresser, though is not particularly obsessive or vain about her appearance.

She was born in London, England in the year 1891 to Dr. Michael Elias, a notable archeologist, and Isabelle Harding-Elias, an artist of British nationality.  Though she was primarily raised in England, she and her mother often traveled with her father on archeological expeditions, living for a year or more in Greece, Turkey, Egypt, and several other places in the Middle East.

As early education was greatly important to her parents, Rosalie spent her formative years under the tutelage of a respectable governess.  She excelled in most subjects, but was always particularly fond of history, likely as a direct influence of her father's profession.  In England, she attended the North London Collegiate School, studying there until the age of fourteen when her family moved to America.  With her father accepting a teaching position at Columbia, his alma mater, their family settled in the Manhattan borough of New York City.  Rosalie was accepted the prestigious Brearley School for girls and graduated in the year 1909.

After high school, Rosalie postponed college to join her cousin Jackson on a grand adventure into the Amazon.  It was her first excursion into the wild rainforest of South America and a shocking introduction into matters of the occult.  While the journey was wrought with peril, and the explorers were confronted with many dangers, Rosalie emerged physically unscathed, if somewhat emotionally shaken.  Even so, the trip fed the flames of her adventurous nature and cemented her curiosity for uncovering the unknown.

Her years at Barnard College passed with little incident, though the latter half were spent under the ominous shadow of the Great War.  With England under attack, Rosalie returned to London immediately after graduating to aid the war's many victims as a nurse.  Confronted for the first time in her short life with suffering and death on a massive scale, the experience changed her in indescribable ways.

Upon the war's conclusion, Rosalie took to traveling the globe in a vain attempt to outrun memories of blood and violence.  Sometimes she ventured to exotic locations with Jackson, and sometimes she simply left on holiday with her parents or friends to experience beautiful places in the world that had not been tainted by the war.  In more recent years, Rosalie has settled in New York City and works there as a historical consultant and researcher to various museums and universities.

Though lingering emotional scars and her thirty-four years have somewhat subdued her once bubbling, vibrant personality, Rosalie still remains a lovely young woman with a sweet and caring nature.  Her intelligence is immediately apparent to anyone attempting to make her acquaintance, and no one could ever dispute the passion she carries for exploration and historical fact-finding.  She is thoughtful and contemplative rather than brash or headstrong, but is not afraid to offer a her opinion when pertinent.  While her manners have been refined by wealth and education, she has never taken her privilege for granted or shown any contempt for those of lesser means.  If anything, she has a natural, quiet charm that draws others to her and promises easy friendship.
