Fort Anaxes, the abandoned Clone Wars-era Republic base was originally designed for the unfinished "Bad Batch" arc from Star Wars: The Clone Wars (2008) which was never broadcast but shown in unfinished form at Celebration Anaheim in 2015 and subsequently released on the Internet.
The "Bad Batch" arc was eventually completed and included as the first arc of the 7th and final season of Star Wars: The Clone Wars (2008) in 2020.

The working title for "Out of Darkness" was "Repairs".
Parts of Fort Anaxes are similar to the rebel Echo Base on the planet Hoth as seen Star Wars Episode V: The Empire Strikes Back. Since the final season of Star Wars: The Clone Wars was released in 2020, fans have wondered if Echo Base is named for the clone trooper Echo who became known as the Hero of Anaxes after he used Separatist intel he gained during his captivity with the Techo Union to beat Admiral Trench and win the Battle of Anaxes.
