Chamra Vortex
The Chamra Vortex was a nebula in the Rakhari sector, in the Gamma Quadrant. The vortex had millions of asteroids and was riddled with pockets of toh-maire gas.

Croden hid his daughter, Yareth, in a stasis pod in a large asteroid in the Vortex in the 2360s. During his imprisonment on Deep Space 9 for the murder of Ro-Kel, Croden told Odo that there was a Changeling colony in the Vortex. 

Odo and Croden traveled to the Vortex, where they rescued Yareth. Ah-Kel followed and attacked them, but his weapons fire ignited the toh-maire gas, destroying his ship. ()
