Thunder and Flame was scribed by a Rune-keeper of ancient Khazad-dûm, known to have been an advisor to King Durin himself. It is said that this ancient tome held many secrets of the Angerthas, passed down from the earliest days in the First Age. It speaks at length of the subtleties of the Cirth script, and how to draw forth the powers of the elements: of fire and storm and winter's chill, for use against one's enemies.

In the end, however, even this vastly complex might was not enough to sate the greed of the dwarves, nor prevent the destruction wrought upon Moria by the awakening of the ancient evil that slumbered in the deep.
