Terminal Box

The Terminal Box is a massive box encompassing a huge portion of the First Realm, and also seems to have a portal to the Alternate Omnipyramid, a massive structure in the Second Realm. It is solid and liquid, digital and physical. There is no civilization. Every now and then a Yetmmud will travel through the portal to the Terminal Box. It also is constantly decreasing in size, but at an extremely slow rate. It is theorized that when it becomes smaller than The Ultimate Box, catastrophic events will occur.
