Human castaway on a planet light years from earth,
Balzan had known many unearthly creatures in his alien home. The cat people had raised him and given him feline knowledge; the winged Aeri had adopted him; beautiful Ryla had loved him in spite of his naked, wingless shoulders.
Now Balzan was being held captive by another tribe of winged humanoids, living deep in underground caverns lighted only by glowing fungi. In this strange world where all women were the wives of all men, where no one was owner or owned, Balzan was plunged into terrifying adventure…with the slimy, gigantic night crawlers…with the most horrible monster of all, the fiendish Sl’yth!
