Z'Tarnis Nebula

The Z'Tarnis Nebula was a Mutara-Class Nebula at the border of the Romulan Neutral Zone. In 2370 the Nebula was the hideout for the Chodak Unity Device, which was sent there through time from the distant past. A Romulan fleet which entered the Nebula in persuit of the Device was destroyed. Later the USS Enterprise (NCC-1701-D), the Garidian Warbird Asyrum and a Chodak Cruiser also entered the Nebula seeking to find the ancient device.
