What do we 'know' about the real Tesseract? who made it? what's it used 'for'?
"A Wrinkle In Time" introduced it: "Mrs. Whatsit, Mrs. Who, and Mrs. Which turn out to be *supernatural beings who teleport Meg, Charles Wallace, and Calvin O'Keefe through the universe by means of a tesseract, a fifth-dimensional phenomenon explained as folding the fabric of space and time; this form of travel is called tessering."
God's Angels can go anywhere, but the fallen angels are restricted, who are these 'supernatural beings' using kids to do what they can't do?
"The three Mrs. Ws tesser the children to the edge of the inhabited part of a dark planet named Camazotz, which has succumbed to The Black Thing, and where the Mrs. Ws cannot themselves enter."
