Vallis was a female Human in the early 22nd century, who was among the passenger aboard the early Earth colony ship SS Mariposa. In 2123, Vallis was part of a scientific mission to colonize a planet in the Ficus sector. Tragically, the ship crash-landed, killing 289, and leaving Vallis as one of only five survivors. This small group then turned to cloning in order to propagate. Vallis became the Progenitor of numerous clones over the following decades, including Elizabeth Vallis and Doctor Sandra Vallis.
