General Claudius Areleius and his twin brother Major Salus. They are the eldest of the Devil's Own, and the only surviving members of the first generation. They are dhampirs, as were their other 10 brothers, specifically raised to protect their vampire father, Lord Damien.
Want to know more about them? Currently I am reposting "The Rise of the Crimson Death" in which Claudius and Salus play a major part.
