Ah yes, the mysterious, timeless non-space that lies between the planes. Okay. First imagine the square root of a negative number. Then picture an eleventh-dimensional solid with that many sides that is somehow humming the Flight of the Bumblebee backwards. Then stuff that whole theoretical construct into a temporal bottle rocket and fire it into a sped-up Big Bang of unfettered imagination, and then squash it down to a momentary singularity of nothingness that is somehow simultaneously infinite and eternal at the same time, and somehow both a specific place and the exact opposite of whereness at the same time, and then add a dollop of nacho cheese. Then give up trying to build a mental image of the Blind Eternities because nuh-uh.
