■, created by ▓, is the source of Industrial Disease, and occurs only when all the 4 main elements (water, fire, earth, and fun) combine in a process that has not yet been discovered, but that some believe involves lost car keys as a catalyst. But since asdfologists really are good and know what they do, it is widely known that ■ is the soruce of all energy, including that which feeds interstelar creatures, like the Xel' Naga and the Boltano bull (not to be confused with interstellar creatures). Some people believe that in the year 1337 AC the power of the ■ will be so great, that even Superman will be nothing compared to it.
