'''Octarian domes''' are the main locations of the [[Octo Valley (mode)|Octo Valley]] and [[Octo Canyon (mode)|Octo Canyon]] missions, as well as the location of the [[Shifty Station]]s.

==History==
When the [[Octarian]]s lost the [[Great Turf War]], they were left to reside in a few locations like [[Octo Valley (location)|Octo Valley]] and [[Octo Canyon (location)|Octo Canyon]]. These areas consisted of several underground domes that were filled with ancient [[human]] structures. The Octarians used these ancient artifacts to create most of the obstacles and mechanics seen in the games.

During the events of {{S}}, the domes in Octo Valley were deteriorating due to a loss of energy causing most to be uninhabitable. [[DJ Octavio]], the Octarians' leader, then decided to steal the [[Great Zapfish]] from [[Inkopolis]] for his own Octoweapon and used all the other [[Zapfish]] to power the domes.

In {{S2}}, [[Callie]] was kidnapped and brainwashed by Octavio. According to [[List of Sunken Scrolls in Splatoon 2#Scroll 23|Sunken Scroll 23]], Callie was put in charge of redecorating the domes to look more upbeat. This is why several banners, stickers, and balloons can be seen in all of the domes. It is also implied that these are the domes that the Octarians moved to after the constant deterioration of the Octo Valley domes.

==Description==
The [[Octarian]] domes are caves with several large television screens broadcasting the outside sky. Each dome includes a giant lamp that brings light into the entire cavern. They also contain several other floating objects like boulders, buildings, and railways.

While the domes in [[Octo Valley (location)|Octo Valley]] only serve as battlegrounds for protecting the [[Zapfish]], the ones in [[Octo Canyon (location)|Octo Canyon]] are also shown to have many other varieties like cities and resorts. The "city domes" have several suction cup-like buildings scattered along the bottom of the area. The sky panels here also have a hexagonal shape and are neatly placed, unlike the other domes. The "resort domes" are filled with water at the bottom of the cave along with a few islands along the sides. The sky panels also broadcast more tropical scenery. The third type of dome also appears to have a more basic cave design, though it does appear to have several roads going across the bottom and top of the dome. Like the resort type, they also are filled with water at the bottom of the cavern.

The [[Tide Goes Out (mission)|final fight]] with [[DJ Octavio]] in Octo Canyon also takes place in his own "concert dome". This dome has several seats along the walls of the cave for Octarians to view the battle. There are also a few additional panels that broadcast close-ups of [[Callie]] and Octavio during the battle. This dome also seems to be filled with a lake of purple [[ink]] instead of water.

==Trivia==
* The official Japanese {{S}} Twitter account stated that [[Octo Valley (location)|Octo Valley]] "was made using the remains of an ancient civilization. It seems to be using very familiar things... or is it just my imagination?" This was an early hint that ''Splatoon''{{'s}} events take place on Earth, long after [[human]]s have gone extinct.
** ''[[The Art of Splatoon]]'' has a comic about the game's backstory, revealing that the [[Octarian]] domes were originally built and used by humans as a means to survive the rising sea levels before they eventually died out. The Octarians seem to not know that the humans created the domes in the comic.
* Boss battles feature a quiet but startling [[Media:Boss mission background sounds.oga|mechanical ambience]] accompanied by screeches and moans that sound similar to [[Zapfish]] cries. This usually cannot be heard due to music and sound effects during gameplay but is easy to listen to before and after battles. The source of these eerie noises is unknown. When asked about the noises, ''Splatoon'' director Tsubasa Sakaguchi responded "It's the first time I've heard this! I was the one who was in charge of the mechanics and the effects for the final boss. Towards the end, though, I was running out of time so I was asking the staff around me to do things for me - like the staff [[credits]] and many other things. Maybe it's a curse from those other staff. The final boss was one of the last things that we were working on. We were all high on adrenaline. Maybe there's some element of that in there, of that energy in there. Once I go back to Japan, I'll play it and have a look."
* The [[Shifty Station]]s (aside from [[MC.Princess Diaries]]) appear to be built in Octarian domes or at least share many similarities with them, such as having floating objects and octopus-shaped rocks. This is due to them being built by [[Marina]].
