Name: Romulan
Homeworld: Mol'Rihan
Federation Membership: Allied
Ease of Writing: Difficult
While we understand a lot of people want to write former Tal Shiar agents or Tal Shiar aligned characters, they are a very small and selective group. If you would like to include service in the Tal Shiar as part of your character, please ask first.
This species is allied with the Federation. If your character applied to Starfleet Academy before 2410, they will have required a letter of recommendation from a Starfleet officer ranked Commander or higher. If this was after 2410 (with the establishment of the Khitomer Alliance,) they could apply without the letter. Alternatively, your character can be an exchange officer or a total transfer from their home faction's forces. If you go with the latter, you must include why they chose to swap to Starfleet.
777 also has a number of roleplayers who have established Romulan houses. For information on these, you can check the Romulan Families document.
Be aware that the Romulans practiced slavery of the Reman species up until 2387. Any Romulan character may have a family history of this.
Due to the complicated history of the Romulan people, there are quite a few things to keep in mind when creating Romulan characters. Keep in mind this is just an outline of major events for reference. The STO Wiki also has a detailed article here!
