The Disc

 The Disc  is a metadimensional circle that loops the hierarchy from the Protoverse all the way to Infinity and Beyond, such that the hierarchy from the Protoverse to IaB is represented on the edge of the circle, with your progression through it being represented by rotating around the circle clockwise. Once you reach a point in the circle, you'll end up back where you were.

There is a cult verse in The Disc called The False End-All-Be-All, making you believe there is a loop. However, this is confirmed to be false. Stated by Alphasm, the only way to escape The Disc is to progress in the hierarchy such that on the circle's edge, you'd be moving in the 2nd dimension. If you were going beyond IaB normally, you aren't shrinking, just entering a much larger iteration of the Protoverse.

Anything that's beyond the power of the Bongus after the first loop is called an Ömë-Töpö Mägö.
