Alsara: Requiem and Revolution
She was the second in command of the organization called the Silent; a demon hunter by trade. Trained as a soldier in the Topos Mathesis, Nadia was a capable officer and Magi in the service of the Silent, and led its forces in battle for all of the Silent’s existence.
When Ivan Vlasi was driven mad by his paranoia of demons and abandoned leadership of the Silent, Nadia was the logical replacement. She led well, and led from the front, doing much to preserve her people and the Grand Marshal. At the end of the Bastion Conspiracy, Lady Catherine Alanis recommended her for the position of Master Emissary.
Whether she accepted, or was elected to the position, is unknown.
