History
The Mogai class was most likely made in response to the Klingon Negh'var class or the sovereign class starships. The IRW Valdore, flagship of Commander Donatra of the Romulan Imperial Fleet, was Mogai-class. 

The commanders of several Mogai-class warbirds were loyal to Donatra, the vessels later came to make up part of the fleet of the Imperial Romulan State once Donatra declared its existence and herself to be its empress.
