Mephodiy has found Drevinir’s blade, a new master for it—Gopzii Rurius the Third, a dashing handsome fellow from Tartar. But Meph doesn’t want to give up the sword. Is there a way to keep it? Arey is sure there is. Duel Gopzii. Rumor has it he is the fourth blade of Darkness. Meph has only a month to prepare. But Buslaev doesn’t yet know what trap Ligul and Gopzii are setting for him.

At the moment of the duel, the power in Meph’s blade will be less than in any museum piece of iron!..
