Cartouche III

"I have carried on the work of my forebears - filching from the wealthy to feed the impoverished. And I have plied my trade well. Yet here I find myself an old man, stretched thin and slowed by time, eager to find another to carry on my work, and bear the name Cartouche into a new century."

- Cartouche explaining his desire to find a successor.

This French Assassin, was a member of the French Brotherhood during the French Revolution.

He was the third incarnation of Cartouche, and the heir of Louis-Dominique Cartouche, a legendary French highwayman, gang leader and womanizer, known to steal from the rich and give to the poor and who later joined the Brotherhood after his "execution". Cartouche subsequently recorded his story in a diary, which he passed on to a younger Assassin prior to his death, so his legend could live on with a new Cartouche.

By the time of the French Revolution, the third incarnation of Cartouche had become an old Assassin that had lost the diary to the Templars. Through chance, he encountered Arno Dorian and requested his help in getting the memoirs back.

Though skeptical of Cartouche's claims, the young Assassin agreed to the task and, upon completing it, earned the old man's approval. Cartouche then revealed that he was looking for someone to succeed him and informed Arno that he could potentially be that person.
