Star Trek Online, you're going to have to deal with Empress Sela no matter your faction of choice. She is the head and the will of the Romulan Star Empire, mastermind of secret alliances and conspiracies aimed at keeping the Romulans as unapproachable and dangerous as they were before the death of their homeworld. But who is she? If you're not up to date on all the details, the latest lore entry from the official site brings you up to speed on the origins of the Empress and her motivations.
The daughter of a Romulan admiral and a time-traveling Enterprise crew member from an alternate reality, Sela tried many times to take power, only to end up in exile before the nova that destroyed Romulus. Undaunted, the loss of her homeworld gave Sela a new means to seize control, ultimately rising to be the new Empress and a staunch enemy of the Romulan Republic. Get the full rundown in the official entry and start getting ready, because all factions -- Klingon, Federation, and Romulan Republic -- will have to deal with her before long.
