Xindi



The Xindi (pronounced "ZIN-dee") are an alliance of species who evolved on the same planet in the Delphic Expanse, known as Xindus. In the early 2150s, they committed an infamous attack on Earth and made repeated attempts to terminate humans, which changed the course of history and initiated a series of events that helped establish United Earth as a major interstellar power. In at least one future timeline, from where Daniels originated, the Xindi state had, by the 26th century, become a member of the United Federation of Planets.

In When the Cold Breeze blows Away, the Xindi, after having formed the Xindi Federation, then joins the Grand Alliance instead of committing an infamous attack on Earth and make repeating attempts to terminate humans.
