M. de Chevallier's Weapons

M. Ratel's Merchants was a virtual representation of one of Aveline de Grandpré's genetic memories.

Description
Aveline came across a concerned citizen, who relayed their troubles of Monsieur de Chevallier.

Dialogue
Aveline met with the concerned citizen.
 * Citizen: Mademoiselle Aveline, I have an important job for you.
 * Aveline: Shoot.
 * Citizen: You might not imagine that gunsmiths are wealthy but–
 * Aveline: With the number of guns I go through? You might be surprised.
 * Citizen: I stand corrected. Then it will come as no surprise to you that a wealthy gunsmith, Monsieur de Chevallier hides in his manse, controlling the prices of weapons across New Orleans.
 * Aveline: I'll find him and arrange for a permanent discount.

Outcome
Aveline assassinated the corrupt business rival and removed his manipulation on the price of weapons in New Orleans.
