Sartai was a Romulan female who held the rank of Commander in the Star Empire's military.
In 2376, she led Romulan forces in an allied task force to Deep Space 9 after the space station was attacked by several Jem'Hadar ships and another Dominion invasion appeared imminent. She later attended a meeting with Federation, Klingon and Bajoran representatives where Taran'atar relayed his mission to them and showed a message recorded by Odo.
Sartai did not believe the Dominion was now devoted to peace, although she was interested in the prospect of her people being able to enter the Gamma Quadrant without the risk of Dominion harassment. (DS9 novel: Avatar, Book Two)
