Hm, I'm not a good'ol'fan of other planes and that stuff, but this sounds like a cooler Div2's Battle Tower and I'm really looking forward the 'Don't forget, this plane exists at the end of time only, and changes according to significant choices you make in the present.' part. After all, we got teleporter pyramids. Who can say they're assertive that they only teleport you inside Rivellon?
