Along with Radue, she visited the USS Enterprise-D that year after the Aldeans had lured the starship to the Epsilon Mynos system in order to reveal the existence of their planet, till then considered only a myth. In fact, the Aldean civilization was millennia old but despite having survived that long the culture was on the brink of collapse as a result of radiation poisoning from the depletion of their ozone layer. The Aldeans had been rendered sterile from ultraviolet radiation, a condition whose impact Rashella felt particularly strongly.
Rashella and Radue led the effort to kidnap the Enterprise's children in an attempt to repopulate their society. Rashella became particularly attached to the youngest child, Alexandra, and refused to turn her over to her unit, the Aldean social group that would be responsible for Alexandra's well-being and education.
However, when the true cause of the planet's ills was revealed, Rashella took the lead in acknowledging the failings of their society's dependence on the Custodian (the planetary computer which had protected them for so long) and vowed to relearn what had been forgotten.
