Our hero Dogtanian is a brave and fearless country pup who wants to be a musketeer. On his journey he falls in love with Juliette and becomes friends with Pip, Aramis, Athos and Porthos. Dogtanian is the best swordsman in France (beating Count Rochefort, Widimer, The Blue Falcon and loads of the Cardinal's guards), he's also prone to thinking with his sword and has excellent dress sense.
D'Artagnan was Charles de Batz-Castelmore, born in Lupiac not Béarn. He became a musketeer in 1645 (3 years after Richelieu's death), and when the musketeers disbanded became Cardinal Mazarin's (Richelieu's successor) personal bodyguard. He also became (the unpopular) governor of Lille before returning to battle in the Franco-Dutch war, dying in the siege of Maastricht.
