Introducing... Thalis

CONAN and his companion Natala are lost in the ancient city of Xuthal. During their wanderings they stumble upon Thalis,

She was tall, lithe, shaped like a goddess; clad in a narrow girdle crusted with jewels. A burnished mass of night-black hair set of the whiteness of her ivory body. Her dark eyes, shaded by long dusky lashes, were deep with sensuous mystery.

Thalis wants to keep CONAN for herself, and tries to despatch Natala. It doesn't end well for her.
