The Natives were a sentient race from a planet in the Stirnis star system, called the Tiffnaki, the Tivvnafi, Vanaffi and the Vanimastavvi by the race themselves. The race possessed high intelligence quotients.
In the year 2373, Cardassian and Drek'la forces invaded the planet. The crew of the Federation Starfleet starship USS Defiant later arrived to act as advisors to the Natives on how to repel the invaders. (DS9 - Rebels novels: The Conquered, The Courageous, The Liberated)
