Serralonis was a world that Kullbee Sperado was on when he was recruited by Saw Gerrera to join the Partisans.
The Star Wars: The Bad Batch introduced a similarly-named planet Serolonis, but the episode guide alternates between the spellings "Serolonis" and "Seralonis", leaving it unclear as to whether it was intended to be the same planet as Serralonis.
