The Great Tesseractagonverse refers to a verse with infinite dimensionality and an unknown shape. The Great Tesseractagonverse contains the entirety of ???, with that only being in the centre.
The outside of this verse is completely unknown, but the shape is definitely fractional-dimensional because every whole dimension was tested using Unkbara's Dimensional Telescope, including all negatives.
This is where the Tgon Entity decided to place all the junk, making this verse pretty much a landfill. Once, a bit of junk fell into ???, which caused a massive break in space-time and revealed the existence of Tgon.
This verse has about 10,000,000,000 pedestals scattered around the place. They are made of metal. These have no purpose, but they are pi-dimensional.
