Selta

 was a Keltan. She went looking for the Eighth Doctor and wanted to know why the Doctor spent a lot of time fixing a ship. She later rescued Lucie Miller from the sea and took her tights. Selta was secretly in contact with the Molluscari, who promised to save her and her family from the coming disaster. She accidentally killed Saccostrea with the Doctor's sonic screwdriver.
