During the Clone Wars, the world indirectly supported the Confederacy of Independent Systems, due to Tambor's allegiance with them. As a consequence, following the end of the war the Galactic Empire placed emigration restrictions on Skako and caused its people to suffer greatly, although many Skakoans were happy to remain isolated from the galaxy on Skako.
Located in grid square L-9 on the Standard Galactic Grid, the planet Skako sat between Brentaal and Fedalle on the Hydian Way hyperspace route. The world had a high-pressure methane atmosphere that to offwordlers was uncomfortable at best and deadly at worst, with even non-native methane breathers finding the pressure unpleasant. Rich in metallic resources, Skako was developed into an ecumenopolis by the technology focused Skakoan species native to the world. The planet's dense upper atmosphere consisted of an alkaline haze due to solar strikes.
Skako was first mentioned in the new Star Wars canon in a featurette included in Star Wars: The Clone Wars The Complete Season One, a box set available on Blu-ray or DVD that included the entire first season of the canon animated series Star Wars: The Clone Wars that was released on November 3, 2009. The world was then pictured for the first time in Star Wars: The Force Awakens Beginner Game, a roleplaying game released by Fantasy Flight Games in 2015. The world originated in the Star Wars Legends continuity, where it was created for Cloak of Deception, a 2001 novel written by James Luceno.
The similarly named world of Skako Minor was introduced to canon by the "Bad Batch" arc of the Star Wars: The Clone Wars television series, which was originally released as unfinished production reels in 2015. During the episodes set on Skako Minor, characters refer to the world as just "Skako" several times, and Anakin Skywalker referred to Skako Minor as "Skako" in the 2019 book Choose Your Destiny: An Obi-Wan & Anakin Adventure. However, the 2018 role-playing supplement Fully Operational clarified that Skako and Skako Minor were separate worlds. A trivia gallery caption in the episode guide for the episode "A Distant Echo" also erroneously describes Skako Minor as "home" of the Skakoan people, rather than Skako.
