Omarion Nebula

The Omarion Nebula was a nebula located inside Dominion space.

In 2371, a joint fleet was launched by the Cardassian Obsidian Order and the Romulan Tal Shiar to eliminate the leaders of the Dominion, the Founders, by attacking their homeworld. The combined fleet was destroyed by the Jem'Hadar in what was known as the battle of the Omarion Nebula.
