The Voss Mystic Talan-De conducted a purifying ritual to protect people from the effects of the Nightmare Lands on Voss. The Mystic Ki-Da created this ritual. The ritual is conducted by taking a dark crystal from a cave in the Nightmare Lands; using the crystal to cleanse the corrupted Voss, trapping the darkness that drives them mad; and then finally taking the crystal to the ruins, placing it before the ancient tablets and meditating to gain Ki-Da's wisdom.
