Merlin's blade

Druids, using a meteorite that has crashed near a small village, try to destroy King Uthur's kingdom and the new Christian faith, and the only person who seems to be immune is a young, shy and half-blind son of a swordsmith named Merlin but when young Arthur, who will one day become the legendary king, is placed in danger, Merlin must face his fears and blindness to take control of the role God ordained for him, only armed with a sword he helped to forge.
