More than half the wealth of Orzammar comes from a single, extremely rare substance: Lyrium. The Chantry believes it to be the "Waters of the Fade" mentioned in the Canticle of Threnodies, the very stuff of creation itself, from whence the Maker fashioned the world. Only a handful of Mining caste families hazard extracting the ore, finding veins in the Stone quite literally by ear. For in its raw form, lyrium sings, and the discerning can hear the sound even through solid rock. —From In Pursuit of Knowledge: The Travels of a Chantry Scholar, by Brother Genitivi.== Related codex entries ==
