In 2401, the location of Yadalla was labeled on a star chart that was seen on the USS Stargazer's bridge viewscreen. The chart was used to show the location of the combined Starfleet-Borg armada and where it needed to go to face a galactic-level threat. (PIC: "Farewell")

This star system was only mentioned in writing.
The name of this system came from the source material used, the Star Trek: Star Charts and Stellar Cartography: The Starfleet Reference Library, to create the star chart seen in Star Trek: Picard. According to Star Trek: Star Charts (p. 45), the primary of the Yadalla system was a F-class star. In the ancient past, about two thousand years ago, Yadalla was a stop on the Debrune trade route.
