Pathfinder III was an exploration ship of the Galactic Republic.
This ship rediscovered the long-lost Human colony of Yashuvhu on 33 BBY. The Pathfinder III crew was on a first-contact mission, so they introduced themselves to the Yashuvhi. They tried their best to learn the Yashuvhi language, only to discover that it was a variant of Basic with inflections, and that the natives were eager to know whether they, the Pathfinder crew, were Jedi.
The crew explained to them what Jedi were. A member of the audience, Force adept Valara Saar, convinced them to take her and her duuvhal, Zeev, offworld to learn the Jedi path.
