The Cannon

The Cannon was a virtual representation of one of Aveline de Grandpré's genetic memories.

Description
Aveline received word from Gérald Blanc about a new cannon design.

Dialogue
Aveline approached a pigeon coop and read a letter from Gérald.
 * Gérald: Aveline, we have intercepted information concerning plans for a new cannon that would prove most useful in defending your trading efforts against pirates. I will provide you the location of the blueprints, but the rest will be up to you. It goes without saying, the plans are highly guarded and stealth is of the highest importance.

Outcome
Aveline managed to sneak into the fort and stole the blueprints.
