Magelord Series by Thomas K. Martin

Around the fires, in the cold of winter, the old tales of the Time of Madness are still told. Tales of MageLords, sorcerers near godlike in their power, who looked upon ordinary men with contempt. Who were still feared and hated--until now.

The Magelord is defeated; the dragon is dead. But a new evil is alive in the land. The king is crippled and helpless by his fear of the Power, and his First Knight, Mathen, delights in hunting down and destroying all those who possess that which is forbidden.All fall victim to Mathen's unreasoning wrath. But a young noble named Ian risks all to forge a route of escape for those in danger -- and on his perilous journey, discovers the Power within himself...

An ancient legend of fear still holds the land in its grip. While those with the Power flee King Gavin's wrath, Bjorn, a simple hunter, discovers that he has this same outlawed ability. Persued by the king's legions, Bjorn conjures an escape -- and is transported into the past. Now he must marshal his ancestors in order to bring those held down by fear to a new future. For the pain and anguish of his memories must never be repeated...
