In this dimension, pockets have developed a life of their own. They have formed a governing body known as the "Council of Pocketed Interests" (CPI) and are demanding equal representation in the fabric of space-time.
Due to the unique properties of pocket fabric, pockets in Dimension 4 can extend up to 1000 km in depth, making them nearly indistinguishable from actual tunnels.
Pockets in Dimension 4 vibrate at an incredibly low frequency, making them nearly invisible to the untrained eye.
In 3004, the first recorded pocket implosion occurred, causing widespread destruction and a brief but intense interest in pocket stability.
As pockets gained sentience, they began to express themselves through bold, neon-colored socks. Today, pocket-themed socks are a staple of Dimension 4 fashion.
