Le Monde de Recluce, Tome 1: Le banni de Recluce

Gunnar, who has kept himself and his family alive using druidic techniques taught by his brother Justen, sends his son Lerris (who is unaware of his father's history and his own magical potential) to Candar to undertake a rite of passage commonly administered to dissatisfied individuals living in Recluce, especially those who have an affinity or ability for either order or chaos. While exiled to Candar, Lerris meets his uncle Justen, and comes to understand his father's ulterior motives for sending him off. Centuries of dominance by Recluce and their order engineers has once again led to increasingly more powerful chaos mages in Candar, with one in particular threatening to cause trouble on the scale of the white council. Gunnar has sent Lerris to Candar with the suspicion that a strong order mage and strong chaos mage will ultimately be drawn into direct conflict, and that Lerris would take care of the problem without Recluce being directly involved. Lerris ultimately defeats the white mage and settles down in Candar to live as a woodworker.
