Astraea was a female Cardassian and a Guide for the Oralian Way. The name "Astraea" is a traditional name assumed by the woman who is to be that generation's guide, a tradition that stretches back to the days of the Hebitians. Following the purge of the Oralian Way in which Skrain Dukat played a major role, this line appeared to have been broken for good. (DS9 novel: Day of the Vipers)
