The nebulous image that hovered before the laughing Good Witch gradually became clear. A narrow glassy tube connected two glass bulbs framed by odd blue wood. Shimmering sandy granules of all imaginable colors filled the bottom bulb. The device mysteriously inverted and the granules flowed from the filled bulb into the empty bulb.
“The sands in the glass will always flow at the same pace. In precisely the length of one light and amber period, or day as you like to call it, all the granules will flow into the lower bulb. At that time, the Day Glass will invert and start the process all over. In terms of the minute minuteman’s unvarying pulse rate, the process repeats after 57,600 heartbeats. My Master has constructed many such devices. In another world, the sands have a nominal running time of one hour and the device is oft called an hourglass. That’d be 3600 minuteman heartbeats. Factors affecting the amount of time the device measures include the volume of the sand, the size and angle of the bulbs, the width of the neck, and the type and quality of the sandy granules,” the female Dream Raider explained.
“I’ve traveled widely throughout the World of the Three Suns and never seen such sand,” Yannuvia remarked.
“In the World of the Three Suns, such sand does not exist. The sands are made from a single Prismatic Dragon scale. They aren’t easy to come by, even for my Master,” Amica proudly declared.
