Biography
They were investigating the enigma of "Eustace", an apparently human skull which had existed before archaeology had estimated humans ever existed. In actuallty, they had found not a human skull, but the remnants of a dormant Fendahl Core.

Taking her prisoner and making her part of a ritual, her co-worker Maximillian Stael and his coven used Eustace to transform Ransome into another Fendahl Core. In this form, she appeared as a golden skinned, majestic, unblinking maiden who could induce paralysis with a glance and transform humans into Fendahleen. (TV: Image of the Fendahl)
