Up in Arms

Up in Arms was a virtual representation of one of Arno Dorian's genetic memories, relived by a Helix initiate through the Helix Navigator.

Description
Arno found a letter to Maximilien de Robespierre from Louis Antoine de Saint-Just which detailed a plot to end the career of Napoleon Bonaparte by delivering defective armaments to his troops. The Assassin set out to destroy the weapons.

Dialogue
Arno infiltrated the workshops and sabotaged the weapons. He then escaped the area.
 * Letter: M. Robespierre, I have succeeded in beguiling some workshops near the Barrière des Martyrs into using defective materials in the manufacture of military armaments. I have further arranged for the defective arms to be delivered to the troops commanded by Captain Bonaparte. I think we can be certain that the young captain's rising star will soon begin to fall. St. Just

Outcome
Arno sabotaged the defective weapons, protecting Napoleon's career from the plotting of Robespierre and Saint-Just.
