Dimensional RP Suggestions!

For all of the people who responded to on of my RPs, "Medieval Quest!", আপনি would know that Glitch has invented a dimensional transporting device. And if আপনি haven't responded to the RP, then there আপনি go. Now, I'm planning to make আরো RPs involving different Mobious dimensions, but right now, I'm having a hard time thinking of one. Then I decided that I'd give আপনি all the chance to come up with your own ideas! Just answer below with the concept of the RP and the dimension it will take place in, along with some info about the dimension. Positive উত্তর only! Thank you!
