Mivek

Subcommander Mivek was a female Romulan Star Navy officer in the early 25th century. By 2409, Mivek was affiliated with the Unification movement and commanded the bird-of-prey starship. She also served as the Unification liaison to allied ships, i.e. the Starfleet and Klingon Defense Force support in the Tau Dewa sector block. 

History
Before the abduction of Empress Sela, Subcommander Mivek served with the Romulan 6th Fleet. Afterwards, command structure became clouded and Mivek decided to support the Unification movement, led by D'tan. 

In 2409, Mivek served as Romulan advisor for the Starfleet science vessel USS Huxley (Nova class), which conducted a survey of the Tau Dewa sector block to help the Unification movement find a new homeworld for the Romulans and Remans. Captain James Wells noted his good working relationship with Mivek. (Star Trek Online: Season 7 Dev Blog #13)

In command of the M'sarr, Subcommander Mivek coordinated the combined Stafleet-KDF rescue effort of Romulan starships captured by the Tholian Assembly in the Azure Nebula.
