Tattyra Firewell was a Human female from the planet Corulag. She and her husband Hondu were both zoologists, and they had a son named Klay.
In 23 BBY, the Firewell family embarked on an expedition to Fondor's jungle-moon of Nallastia to study its fauna, but they were mistaken for poachers and imprisoned by Princess Calvaria. They were only rescued when a Jedi team was able to find the Lost Stars of Nallastia, after which they returned to Corulag.
