Nadia

From Herocopia

Nadia, a young Yugoslavian woman, became Augustus Furst's third wife after he rescued her from a pocket of alien energy.

She left Augustus two years later for Kaspian, with whom she had twins. In 1961, while Kaspian was imprisoned, Nadia vanished and hasn't been seen since. Augustus Furst then adopted and raised her children, Nick and Natalie Furst.
