Kh'ymm, an alien being, managed an age-old telescopic array on the Observatory Moon called Kh’ymm’s observatory. This occurred in the time of the New Republic Era. Kh'ymm used the array.
In 9 ABY, the crew of the vessel named Onyx Cinder journeyed to Kh'ymm's location at the array. They sought a pathway to return to their home planet, At Attin. Kh'ymm utilized her archive at the array and uncovered what she thought were the coordinates for At Attin. However, these coordinates actually led to At Achrann.
The telescopic array made its debut in the Star Wars: Skeleton Crew episode entitled "Very Interesting, As an Astrogation Problem." This was the third episode of the live-action Disney+ series, and it was broadcast on December 10, 2024.
