harvest their victims and their spoils.

"Labyrinthine passages connect these caves with the luxurious
palaces of the Holy Therns, and through them pass upon their many
duties the lesser therns, and hordes of slaves, and prisoners, and
fierce beasts; the grim inhabitants of this sunless world.

"There be within this vast network of winding passages and countless
chambers men, women, and beasts who, born within its dim and gruesome
underworld, have never seen the light of day--nor ever shall.

"They are kept to do the bidding of the race of therns; to furnish
at once their sport and their sustenance.

"Now and again some hapless pilgrim, drifting out upon the silent
sea from the cold Iss, escapes the plant men and the great white
apes that guard the Temple of Issus and falls into the remorseless
clutches of the therns; or, as was my misfortune, is coveted by
the Holy Thern who chances to be upon watch in the balcony above
the river where it issues from the bowels of the mountains through
the cliffs of gold to empty into the Lost Sea of Korus.

"All who reach the Valley Dor are, by custom, the rightful prey of
the plant men and the apes, while their arms and ornaments become
the portion of the therns; but if one escapes the terrible denizens
of the valley for even a few hours the therns may claim such a one
as their own. And again the Holy Thern on watch, should he see a
victim he covets, often tramples upon the rights of the unreasoning
brutes of the valley and takes his prize by foul means if he cannot
gain it by fair.
