The Demon King of Bergher — Glenn G. Thater

When the Demon King of Bergher comes calling with an evil gift that can corrupt a man's soul and devour his will, Lord Torbin Malvegil and all his knights can't keep him out. No gate or wall, no ward or prayer, no army, hero, or wizard's binding can hold the demon back. When all hope is lost, and his ladylove's life hangs in the balance, Torbin takes up his sword and stands alone against the ancient fiend -- prepared to sacrifice all, even his immortal soul, to save his true love. The Demon King of Bergher is a short story set in the same world and featuring some of the same characters as Glenn G. Thater's Harbinger of Doom series of epic fantasy books.
