The Wolf and the Well - Tempered Clavier

With the coronation fast approaching, the Cathedral of St. George the Dragonslayer cannot afford trouble. But come it does, while the cathedral choir director is at the Dragon's Breath Organ, practicing the anthem he wrote at King William's own request. While explaining some technical terms to his understudy, the choir director decides to show off a little. In the process, he releases an ancient menace from long before humanity came through the worldgate to this place.
An entity that strikes him blind, and threatens further harm to anyone who tries to play the Dragon's Breath Organ. However, they dare not disappoint His Majesty, not on the most momentous day of his reign. Someone must cleanse the Dragon's Breath Organ of this malicious entity, and the choir director cannot. So the task falls to Miss Anne Teesdale, understudy organist. Now she must delve into the history of the cathedral, and the mysterious ancient magic that fills the organ's windchest.
A secret that may well cost this young woman her life. Or worse, her sanity. An Ixilon story.
