The Convention of TwelveA secret organization that controls England from the shadows, and is modeled after the Knights of the Round Table. Some members of Parliament, military officers, and a few prominent nobles are among its members, as well as the leader of Hellsing (currently Integra). Integra's father and predecessor Arthur Hellsing (who gets some screentime in Dawn) may have been the "leader" of the Convention, and passed his position of authority to his daughter and Sir Islands. It is likely that membership is hereditary; Sir Penwood informs Integra that this is how he got into the Convention, and the finale reveals that Sir Penwood's grandson succeeded him.
