"Thinkest thou, O fools, that Issus wilt give up her own? Thinkest thou to escape from whence in all the countless ages but a single soul has fled?
"Go back the way thou camest, to the merciful maws of the children of the Tree of Life or the gleaming fangs of the great white apes, for there lies speedy surcease from suffering; but insist in your rash purpose to thread the mazes of the Golden Cliffs of the Mountains of Otz, past the ramparts of the impregnable fortresses of the Holy Therns, and upon your way Death in its most frightful form will overtake you—a death so horrible that even the Holy Therns themselves, who conceived both Life and Death, avert their eyes from its fiendishness and close their ears against the hideous shrieks of its victims.
"Go back, O fools, the way thou camest."
And then the awful laugh broke out from another part of the chamber.
"Most uncanny," I remarked, turning to Tars Tarkas.
"What shall we do?" he asked. "We cannot fight empty air; I would almost sooner return and face foes into whose flesh I may feel my blade bite and know that I am selling my carcass dearly before I go down to that eternal oblivion which is evidently the fairest and most desirable eternity that mortal man has the right to hope for."
"If, as you say, we cannot fight empty air, Tars Tarkas," I replied, "neither, on the other hand, can empty air fight us. I, who have faced and conquered in my time thousands of sinewy warriors and tempered blades, shall not be turned back by wind; nor no more shall you, Thark."
"But unseen voices may emanate from unseen and unseeable creatures who wield invisible blades," answered the green warrior.
"Rot, Tars Tarkas," I cried, "those voices come from beings as real as you or as I. In their veins flows lifeblood that may be let as easily as ours, and the fact that they remain invisible to us is the best proof to my mind that they are mortal; nor overly courageous mortals at that. Think you, Tars Tarkas, that John Carter will fly at the first shriek of a cowardly foe who dare not come out into the open and face a good blade?"
I had spoken in a loud voice that there might be no question that our would-be terrorizers should hear me, for I was tiring of this nerve-racking fiasco. It had occurred to me, too, that the whole business was but a plan to frighten us back into the valley of death from which we had escaped, that we might be quickly disposed of by the savage creatures there.
