Ikalian asteroid belt

The Ikalian asteroid belt was an asteroid belt in the Ikalia system, Beta Quadrant. Some of the asteroids had deposits of actinides.

In 2367, Kriosian rebels, fighting to regain their independence from the Klingon Empire, hid in the Ikalian asteroid belt, using the actinides to hide from sensor scans. While hiding in the belt, they attacked a Ferengi freighter and a Cardassian freighter. (TNG: "The Mind's Eye")

In the script, the pronunciation for Ikalian was "ih-KAY-lee-n". [1]
In the Star Trek Encyclopedia, 4th ed., vol. 1, p. 358, it was stated that the Ikalian asteroid belt was located near the Kriosian system.
