5-Dimensional Basketball

5-Dimensional Basketball, colloquially referred to as 5, is a sport played in the astral realm. It started as a casual game, brought to the astral realm by an unknown visitor coming from Earth in Universe One, but was eventually adapted into a professional sport. The official association for all 5D Basketball teams is the Multiuniversal 5-Dimensional Basketball League (M5DBL).
