Technomagic:
Enemy Unknown

Fate separates the leader of the clan of Tverdislav and the main witch Djeyana the Furious. But what a pity! Would they still be together, it would be intersting to see how it would all turn out, indeed, before their combined Force, most powerful witch magic is easily crushed. But now they are forced to look for the person separately, the person who monstrously experimented on their native planet, who borught so much evil to their kinsmen. And they will not get a minute of rest as long as the ENEMY IS UNKNOWN.
