Yin-Tuan was captain of one of the great war junks of the Cathayan fleet ca 1690 IC. His ship was blown off course by a typhoon that scattered the fleet shortly after it put to sea, and he and his crew crossed Lustria and the Southlands trying to reach the rest of the Grand Imperial Army. He was the only survivor of the whole expedition and Dragon Emperor Wu named him commander of the Palace Guard. Years later as an aged sage living in retirement in the monastery of Mount Li, he wrote down an account of the adventure which survived as a classic of Cathayan literature.[1a]
