The lunar ice bridge existed on the moon Caliban, a celestial body located within the Outer Rim Territories.
This icy structure on Caliban was shown briefly within a flashback sequence in the comic book series Star Wars Adventures: The Clone Wars – Battle Tales, specifically in its fifth issue. Michael Moreci penned the issue, which IDW Publishing released to the public on September 30, 2020. The artwork for the Caliban flashback was created by Philip Murphy.
