Rank in the Romulan Star Empire is less structured than in the militaries of other governments, and it is also less rigid. Two Riovir (Commanders) may hold the same rank, but depending upon their loyalties and connections one may have more power and authority than the other.
Players are capped at Arrain with the exception of the FO and CO. The FO is capped at erei'Riov. The CO is capped at Riov unless the CO is a Fleet Commander, in which case they may be promoted to Enriov. If the CO is at the rank of Enriov, the FO may be promoted to Riov and Division Heads may be promoted to erei'Riov. Exceptions will be made on an individual basis.
