The order of the black tabernacle has stolen the body of its First Crusade co-founder Amir Dyalamon, but didn't capture the main prize, a jewel known as the Eye of Gilgamesh, which that 'dark knight' stole as a renegade. Cardinal Mazarin is convinced that must be the doing of a traitor. His obelisk magic resurrects the crusader, who kills the thief (old knight Ivan Tavarsky), with his broadsword, before Ivan can honor his rendezvous with captain Duvall. Siroc experiments with (electric) energy as the biological essence of life, and is given the 'ordinary' body of wagon driver Latrobe, whom the thief fatally stabbed before the masked knights arrived to examine, as part of the musketeers' investigation. Meanwhile D'Artagnan generously accepts to bow away when Zak's latest flame, Mlle. Dubois, naturally falls for Junior, but they come across the knights and Zak is now viciously jealous. A book in the monastery explains about Amir, the powers of the obelisk, the order, and the Eye, which Zak accidentally finds in the stables where Ivan was hidden, but the dark knight is on its trace.
