The Hyperbolic Time Chamber is a separate dimension from that of Earth. There is no night or day in the Room, but the surroundings remain a constant bright iridescent white aurora. Its reflective floor is of undefined area, and the Room's boundaries are thought to stretch to infinity in all directions even though it appears to have a definite atmosphere, limiting its size to about that of the Earth. Those talking in the chamber have an echo in their voices akin to when a character thinks a word.
