The Magic in the Insane

***This story is in no way connected to Serpent Magic, this idea popped into my head so I wanted to try it out.***

Harley Quinn can rarely keep her mouth shut, so you would normally find her chatting about anything and everything, and so it's not a surprise when the villains of Gotham find out something particularly magical about their fellow criminal. But she isn't the only one with this knowledge but in a world of flying monsters and supermen, who says magic can't exist? So when a certain Dark Lord comes to Gotham for a certain someone, that someone can't help but bring the whole gang with her into the outdated world of spells and flying broomsticks, nor can she help but place them all in a several-year-long adventure, as 11-year-olds.
