They are heroes foretold by the architect and ruler of the palace, the ancient elven wizard Kaligby. He looks to them, across time and space, to aid him in uncovering the ancient evil that has led to centuries of warfare and death. What will the characters find as they walk the history of the Castle in the Sky?
