The Enchanter General

It is 1164, and for a hundred years England has been ruled by the Normans. A young Saxon boy named Durwin, crippled by a childhood accident, had caught the eye of a Norman sage teaching at a rural school of magic. Realizing that the boy had promise, Durwin was made stable boy, and eventually allowed to attend classes. Now twenty, Durwin is proficient enough that he is assigned to teach, but the other sages refuse to promote him and he is hassled by the Norman juniors for his disability.

King Henry, campaigning in France, receives a muddled warning of a treasonous conspiracy in Lincoln Castle, his great fortress in the center of England. His enchanters report that the letter contains both truth and lies, but cannot determine which is which. Putting little stock in the warning, he sends an eager young knight to lead a troop of men and investigate, and since the letter includes hints of magic, Henry orders him to enlist the help of Durwin, the young Saxon whose education he has been financing these last two years.  

King Henry is dead; Richard the Lionheart now rules England. The new king does not believe in magic, and is interested only in a crusade to recapture Jerusalem. But his crusade soon stalls, and while he is away, his brother, John, and his supposed ally, Philip of France, are conspiring to steal his kingdom. Richard's mother, Queen Eleanor, sends Sir Durwin, Enchanter General of England, out to Palestine, where he must convince the skeptical king that a loyal magician can be a valuable aide. Meanwhile, King Philip has turned all of Europe into a trap for Richard.
