"In part, yes," she answered. "That about the outer valley is true, but what he says of the location of the Temple of Issus in the centre of his country is false. If it is not false--" she hesitated. "Oh it cannot be true, it cannot be true. For if it were true then for countless ages have my people gone to torture and ignominious death at the hands of their cruel enemies, instead of to the beautiful Life Eternal that we have been taught to believe Issus holds for us."
"As the lesser Barsoomians of the outer world have been lured by you to the terrible Valley Dor, so may it be that the therns themselves have been lured by the First Born to an equally horrid fate," I suggested. "It would be a stern and awful retribution, Phaidor; but a just one."
