THV Acumen Ensium

The THV Acumen Ensium is a turian dreadnought and Flagship of the Hierarchy's Second Fleet. 
In the aftermath of the Battle of London, the Charon Relay shut down and the combined fleets found themselves trapped within the Sol system. The turians were lucky in that they happened to be very well represented from a governmental standpoint; Citadel Councilor Sparatus, War Primarch Adrien Victus, Praetor Aelianus Vakarian, and later his son Legate Garrus Vakarian after he arrived in the Sol system following the Normandy's reactivating of the Relay. As a result the three, then four, men met regularly on board the Acumen Ensium to help lead their people with the ship acting as the de facto seat of government.
