Named after one of earth's African-American abolitionists and women's rights activist, Sojourner Truth, who was born into chattel slavery but escaped to freedom in AD 1826, the Jaunt-Ship Sojourner whose name was chosen by the family that would pilot her, was created to be one of the first human ships of the late 22nd-Century to use "jaunt" technology reverse-engineered from their alien opponents in the so-called Earth-Xeria War several years before. Sojourner would allow the Strong family to journey across the wide open reaches of outer space with the aptly-named Strong family ready to explore its regions for knowledge and to handle its unknown dangers. The Strongs prove themselves not only worthy of a staunch pioneer spirit but having the bravery and fortitude necessary to navigate the perils and wonders of an interstellar frontier all the while at first unsuspecting the treachery of their own Planetary Coalition in its attempt to seize absolute power from the beneficent Xerians.
