The sorcerer is involuntarily

“Washing is involuntarily” - the first of the main (there is also a prequel) books of the cycle about the sorcerer of Gallowlus. Christopher Stasheff wrote a whole saga about his adventures.
A young man with a technologically developed planet arrives at a gramarium. The colony of wealthy emigrants from highly developed worlds once moved here. And they built themselves according to their ideas either later the Middle Ages, or the early Renaissance ... As they presented and began to live, after centuries, forgetting where they came from and what they knew. And on the planet there is witchcraft, elves and banns, political conflicts and alien intervention. Ironical, philosophical and somewhere even romantic books about a sorcerer involuntarily are one of the best fantasy epic.
