Ordeal in Otherwhere (Forerunner)

An illegal trading venture to the planet Warlock has resulted in a crew-woman going insane due to the mind influence of the females of the pseudo-reptilian Wyverns of Warlock. So the trader captain purchases the "labor contract" of Charis, a former education officer to a fanatic religious colony, thinking because she is female he can use her to contact the witches and induce them to trade with him.
