The Piraka swung his blades.  Tahu barely got this twin magma swords up in time to counter the blow.  Zaktan pushed him away and then thrust again, forcing Tahu to step toward the cliff.  The Toa of Fire caught Zaktan's weapon between his two swords and sent waves of heat up the blades.  But for each fragment of Zaktan's sword that melted, pieces flew from the Piraka's substance to make up the loss.
	"It is not so easy as that," Zaktan said.  "I am my weapon. My weapon is me.  To destroy it, you must first destroy me."
