"Charter" is said to be one of the last known of many aliases used by a famous elven spy for sale and master of false identities nicknamed The Black Hart, who was contacted by Leliana when seeking steady employment. Other suspected aliases include "Mollnir," a double agent who revealed a conspiracy against the crown in Hercinia and "Sonner," who stole a general's plans and walked out in broad daylight in Markham.
Along with being one of Leliana's spies, Charter is also a senior member of the Inquisition and the commanding officer of Caer Bronach. It was also Charter who recruited Scout Harding into the Inquisition.
