He decides to fight injustice as The Defender, and fight for those who cannot fight for themselves. His wife Nancy joins him as The Moon Spirit. Although she can't cast spells, she can fight and use the enchanted equipment Allan crafts.
This volume contains the third group of five Defender stories. The students of the Defender and the Moon Spirit are becoming Defenders in their own right. They're using magic to protect the innocent and bring down the guilty, however powerful the guilty might be. They're also expanding the knowledge of magic to rebuild what was lost when the time of the Great Mages ended.
