Athos
Athos is noble and handsome but also taciturn and melancholy, drowning his secret sorrows in drink. He is very protective of d'Artagnan, the youngest, whom he eventually treats as a son. He was once married to Milady de Winter and attempted to kill her after discovering that she was a criminal on the run, an event which left him bitter and disillusioned.
Twenty years after, he has retired from the Musketeers and abandoned his nom-de-guerre of Athos. He has fathered an illegitimate son, Raoul, with Marie de Rohan and then adopted the boy, making him the vicomte de Bragelonne. Fatherhood makes Athos a much happier man, but after launching Raoul into a military career, Athos looks for new causes to occupy his life.
Ten years later, Athos takes a major behind-the-scenes part in historical events, first helping with the restoration of Charles II to the throne of England, and then being entrusted with the diplomatic task of arranging the wedding of Henrietta of England and Philippe I, Duke of Orléans. Athos eventually falls out with King Louis XIV of France, who has seduced his son Raoul's fiancée, and is briefly thrown into the Bastille for voicing his contempt. After being pardoned at d'Artagnan's instigation, Athos withdraws to his home, where he dies of sorrow after Raoul is killed at war.
