12. Sector E-K 19
The CIA asked me not to tell you about this one on our list of best imaginary island name ideas, but I just couldn’t help myself. Sector E-K 19 is the biggest of many alien colonies in North America; Canada, specifically. It is located near Greenland, and has over 5000 legal alien inhabitants from all around the cosmos; Sting is rumored to have resided here at one time. Thanks to alien technology, the weather is perfect all-year round; however, its existence is a secret, so no one is allowed to go there without the required credentials. I have now given you Canadian aliens.
