Lord Soth was a true and noble knight of Solamnia. But he was an intensely passionate man, lacking in self-discipline, and this was his downfall.
Soth fell in love with a beautiful elfmaid, a disciple of the Kingpriest of Istar. He was married at the time, but thoughts of his wife vanished at the sight of the elfmaid's beauty. Forsaking both his sacred marriage vows and his knightly vows, Soth gave in to his passion. Lying to the girl, he seduced her and brought her to live at Dargaard Keep, promising to marry her. His wife disappeared under sinister circumstances.
The elfmaid remained true to the knight, even after she discovered his terrible misdeeds. She prayed to the Goddess Mishakal that the knight be allowed to redeem himself and, apparently, her prayers were answered. Lord Soth was given the power to prevent the Cataclysm, though it would mean sacrificing his own life.
Strengthened by the love of the girl he had wronged, Lord Soth left for Istar, fully intending to stop the Kingpriest and restore his shattered honour.
But the knight was halted in his journey by elven women, disciples of the Kingpriest, who knew of Lord Soth's crime and threatened to ruin him. To weaken the effects of the elfmaid's love, they intimated that she had been unfaithful to him in his absence.
