Ever Land, a land I made up when I was little.
When I was little I created a place called EverLand, it's the NeverLand's far away twin, but it's mostly the opposite in everyway.
It is inhabited by a girl named Patricia Pot and her MALE fairy and his name is Manglebell, instead of fixing things like Tink does, he likes to tear things up and destroy, hence the name Manglebell.
Patricia is a young girl who wants nothing more than to grow up, often refers to Manglebell as "Mang"
It has an evil villain, Colonell Hook, with a hook for a foot who is terrified of an alligator who ate his foot years ago.
There IS a mermaide lagoon there, but ther mermaids are backward, they have human legs and fish upper bodies.
Just recalled this idea I had as a child thought I'd share it :)
Create a society in which you would like to live, not knowing what you're going to come into it as.
