Turjun, the panthan, was the last to clamber over the rail of the _Thuria_, drawing the rope ladder in after him. A moment later the flier was rising rapidly, headed for the north. At the rail Kar Komak turned to speak to the warrior who had been detailed to accompany him. His eyes went wide as they rested upon the face of the young man whom he had met beside the granite cliffs that guard mysterious Lothar. How had he come in place of the Dusarian? A quick sign, and Kar Komak turned once more to find the _Thuria_’s dwar that he might report himself for duty. Behind him followed the panthan. Carthoris blessed the chance that had caused Vas Kor to choose the bowman of all others, for had it been another Dusarian there would have been questions to answer as to the whereabouts of the warrior who lay so quietly in the field beyond the residence of Hal Vas, Dwar of the Southern Road; and Carthoris had no answer to that question other than his sword point, which alone was scarce adequate to convince the entire crew of the _Thuria_. The journey to Dusar seemed interminable to the impatient Carthoris, though as a matter of fact it was quickly accomplished. Some time before they reached their destination they met and spoke with another Dusarian war flier. From it they learned that a great battle was soon to be fought south-east of Dusar. The combined navies of Dusar, Ptarth and Kaol had been intercepted in their advance toward Helium by the mighty Heliumitic navy—the most formidable upon Barsoom, not alone in numbers and armament, but in the training and courage of its officers and warriors, and the zitidaric proportions of many of its monster battleships. Not for many a day had there been the promise of such a battle. Four jeddaks were in direct command of their own fleets—Kulan Tith of Kaol, Thuvan Dihn of Ptarth, and Nutus of Dusar upon one side; while upon the other was Tardos Mors, Jeddak of Helium. With the latter was John Carter, Warlord of Mars. From the far north another force was moving south across the barrier cliffs—the new navy of Talu, Jeddak of Okar, coming in response to the call from the warlord. Upon the decks of the sullen ships of war black-bearded yellow men looked over eagerly toward the south. Gorgeous were they in their splendid cloaks of orluk and apt. Fierce, formidable fighters from the hothouse cities of the frozen north. And from the distant south, from the sea of Omean and the cliffs of gold, from the temples of the therns and the garden of Issus, other thousands sailed into the north at the call of the great man they all had learned to respect, and, respecting, love. Pacing the flagship of this mighty fleet, second only to the navy of Helium, was the ebon Xodar, Jeddak of the First Born, his heart beating strong in anticipation of the coming moment when he should hurl his savage crews and the weight of his mighty ships upon the enemies of the warlord.
