Mage Jorlan is on his way from the capital to Duchess Linten's castle when he runs into the Knights of Darim, who hate mages and threaten to kill not just him, but all mages in the area. They take him captive, but there are still mages in the forests of Kastum who will stand against the Knights. One of them is earth mage Tahik, who frees Jorlan, taking him into a rebel camp. They grow closer, but the Knights of Darim will not just vanish, and the mages are running out of time as winter approaches.
