"Weird place, isn't it?"
EMPOWERED POWER RAIL 5V is a black and anomalous dimension contained by the RSCP Foundation. The dimension has a floor that somehow creates an unchanging static potential difference of five volts. It's space is also non-Euclidean, meaning it also warps reality so that a Robloxian, upon walking 100 meters in any direction, would see a Portal to Reality in their direction. If they continue walking towards the direction, they will enter the RSCP and be sent to the Reality dimension.
