Power Matrix - Absorbs and Releases Energy

At its heart, in a small raised room done in crimson, the Power Matrix resided within a large case of thick glass. It was magnificent.

The main body of the Power Matrix was a single enormous white crystal, nearly the height of a man. All along its faceted outer edges, other smaller stones in blue, green, red, white, and black were affixed. They seemed to pluck each strand of the spectrum out of the room's dim light and send it lancing into the central crystal. A network of metal wires connected the stones, and along the wires moved scintillating jolts of energy. It was a mesmerizing sight.

"We must keep the room dark," the grand vizier told her guests, "for the Matrix stores and channels energy. Were it to be exposed to sunlight, the stored energy would quickly cause the Matrix to explode."
