So, what made you think of genies? On Wonderland (the place where genies are actually more detailed), the genies are likely cursed humans by a particular deity/guardian or an errant wish (I won't spoil it as the spinoff was quite good).

On a side note, genies are trapped in many vessels besides lamps. There are genies in bottles, lamps, rings, and on Once in mirrors, so they can be diverse.
