In 2370 Ttan volunteered for her and her clutch of twenty eggs to travel to Bajor to help revitalise the Bajoran mining industry. A Federation cruiser, the USS Puyallup, was specially fitted to accommodate her on the journey, filled with synthetic concrete to simulate Ttan's usual rocky habitat. As the ship was nearing Deep Space 9 it was attacked by a Cardassian vessel and Ttan was kidnapped.
Ttan awoke to find herself suspended in midair, and panicked, squirting her acids. She was greeted by her captor, Gul Mavek who told her he had her eggs and she would have to cooperate to ensure their safety. She was taking to the mining moon Davonia and instructed to search for latinum, which she did, but not fast enough for Mavek who refused to allow her to see her eggs.
Mavek continued to blackmail Ttan until she was rescued by a team from Deep Space 9. They informed her that her eggs were safe on the station. In revenge for what he had put her through Ttan dissolved Mavek, killing him.
- Ttan is first identified as Titan however the name is consistently spelled as "Ttan" throughout the rest of the book.
