"It will be," said Xodar, "when they find from whence you have come. That is but one of the superstitions which Issus has foisted upon a credulous humanity. She works through the Holy Therns who are as ignorant of her real self as are the Barsoomians of the outer world. Her decrees are borne to the therns written in blood upon a strange parchment.
The poor deluded fools think that they are receiving the revelations of a goddess through some supernatural agency, since they find these messages upon their guarded altars to which none could have access without detection.
I myself have borne these messages for Issus for many years.
There is a long tunnel from the temple of Issus to the principal temple of Matai Shang. It was dug ages ago by the slaves of the First Born in such utter secrecy that no thern ever guessed its existence.
"The therns for their part have temples dotted about the entire civilized world. Here priests whom the people never see communicate the doctrine of the Mysterious River Iss, the Valley Dor, and the Lost Sea of Korus to persuade the poor deluded creatures to take the voluntary pilgrimage that swells the wealth of the Holy Therns and adds to the numbers of their slaves.
