Olivia Darque
Overview
Olivia Darque is a villain in need of rescue. She belongs to the Arachnos faction and can be found in the Secure Olivia Darque from the Longbow ambush mission from Peter Themari.
She must be freed from her Longbow captors and escorted back to the mission exit. Once free, she will aggro on everything nearby, and her aggro radius is fairly big, so she may get in trouble if you don't keep an eye on her. She may be in danger if you didn't clear the path before freeing her, as waves of Longbow ambushers (including a boss-level hero) will come after her.
Olivia Darque spawns as a Pet of the level of the mission owner plus one. She must survive for the mission to be successful.
Description
The assistant to Marshal Brass is one of the big players in Cap au Diable. Do right by her and you may be well on your way to greatness. Let Longbow defeat her and your life won't be worth much.
Quotes
Once you free her:
Olivia Darque: You better do right by me, Villain, or Arachnos will hear about it
At the mission exit:
Olivia Darque: I'll remember you, Villain
Powers
She used a combination of Dark powers during the way back to the mission door. I remember Gloom and Shadow Maul among others, but I'm not positively sure about what she used concretely.
