Mosliorae

An old dialect of Romulan, an offshoot that emerged when the Romulan language was fracturing from the Vulcan language after the Romulan people left Vulcan society behind. It was mostly abandoned after what become the common Romulan tongue started to be adopted by enough of the people, but some scholars and the Tal Shiar have both been known to keep it alive. Very few outside Romulan society even know of its existence.
