The Prodigal Sorcerer — Mark Sumner

BEHIND THE MAGEWALL
For centuries, the magewall has isolated a battletorn valley. There, three races live in perpetual strife fueled by prejudice and fear. The Vashino hate the Garan, the Garan loathe the Humans, and the Humans despise them all.

But a new day is dawning. Tagard Tarngold, a human leader, has a plan that could bring harmony to his war-ravaged home, and has enlisted the aid of Aligaurius, a sorcerer from the Institute of Arcane Studies, in his efforts.

Peace may be on the horizon at last. But the terrible price of Tagard's peace may be more than his people can pay.
