Tesseractverse

The Tesseractverse is a verse that has spherical geometry. That means that if you go in one direction for long enough, you will get to the same place you started in, and angles of a triangle sum to more than 180°.

While the verse doesn't exist in a tesseract, there are blue structures that replicate the {4,3,3} honeycomb, which means three cubes around a vertex. The purpose of these structures is unknown.
