The Imperial Xenodetic Survey department functioned as a division within the Galactic Empire. Within this department, a recording clerk altered a record pertaining to the Yavin system, specifically renaming the planet designated 96NK3F2 to Fiddanl. Notably, "Fiddanl" was a common affectionate term used by members of the Nuiwit species.
