A barely habitable planet where Salia, future ruler of Daled IV, was brought up in isolation for sixteen years before the Enterprise-D collected her in 2365.
Klavdia III is an inhospitable planet featured at the start of the second-season Next Generation episode The Dauphin.
Salia was born to parents from the two warring sides of Daled IV, a world on which one hemisphere is always in daylight and the other always dark. So that she could grow up neutral, she was taken as an infant to Klavdia III and raised there with only her guardian Anya for company, studying for the day she would return to unite her people.
In 2365 the Enterprise-D arrives to take the pair home. The crew are surprised that anyone could have lived in such conditions for so long. During the voyage Salia and Wesley Crusher fall for each other, and it emerges that both she and Anya are allasomorphs, able to take many forms.
