Tyree
From Star Trek : Freedom's Wiki
Tyree is a desert planet located in a binary star system where the Orb of the Emissary was hidden. Despite being Class M, the planet was desolate and uninhabited, and was enveloped by an ionized atmosphere that interfered with ship sensors.
In 2375, Benjamin Sisko traveled to Tyree with his father, son, and Ezri Dax to find the orb, after receiving a series of visions. After unearthing the orb, Sisko opened it and released the Prophet who inhabited Sarah Sisko into the Bajoran Wormhole. (DS9: "Image in the Sand", "Shadows and Symbols")
