Tattyra Firewell was a female Human originating from the planet of Corulag. She worked as a zoologist alongside her husband, Hondu, and together they had a son named Klay.
The Firewell family undertook an expedition to Nallastia, which is a moon with a jungle environment orbiting Fondor, in 23 BBY. Their goal was to research the local wildlife. However, they were wrongly accused of poaching and subsequently imprisoned by Princess Calvaria. Their liberation occurred only after a Jedi team able to find the Lost Stars of Nallastia, leading to their eventual return to Corulag.
