From the introduction: In a field of ice so large it takes many cycles for a Shoveltusk herd to cross it, one may find a standing stone—pulled from beneath the frozen tundra by a strength fueled by tears of devotion which still glow inside of it. The stone glows each time a breeze presses into its sharp and shining indentations and pulses each time the earth shakes. It wants to share its song with any brave or wandering soul that comes upon it. Its memory is perfect, and it knows the Pyroi in a way few Pyroi do.
