Olivia Darque is assistant to Marshal Brass of Cap Au Diable in the Rogue Isles. Olivia is only seen on few missions and rarely mentioned, however she is still seen as one of the more important officers of Arachnos partially because she manages Cap-Au-Diable, one of the most busy cities within the Rogue Isles and partially because she is sidekick to Marshall Brass, one of the most decorated Arachnos soldiers who is not an Arbiter or within Lord Recluse's inner circle.
