over a 1000 years from now there was a war between squid peapol called inklings and octopus peapol called octolings. while it was harde the the inklings won and the octolings hide in underground city's and fortresses were there leaders ploted reveng while most made it to octo valley and octo canion though others split up and ended up bilting ther citys and bases in a sub way network that wood become the deep sea metro and founded kamabo co evently they found the ancient human ai tar tar (eather now or before the grat turf war depending if he did tech octarians to bilt underground citys ) who gave then the human knowledge in exchange he became the ceo 1 camander and even builted giant size meshins resembling human devises like game cubs and game boys any ways tar tar started to hate inkopoles a city full of inklings and wanted to replace them and started bilting a milatery out of the kamabo octolings and slime that can turned them and inkling into mindless zombe shoulders with the soul porpous to follow his orders and others became test subjects along with other creachers. at some point to mack more test subjects he or she started to loer and kidnaped more ocolings building supway stations closser to octarian citys (wicth is wy you can here them in boss rooms ) and no won new what he or she was doing until the squid beak splatoon forces took the commander down
