you can find her:

 

 

To find this new companion you'll need to follow the main questline until you reach Galvino's hut. Follow the trapdoor in the right room to find a cavernous area of rooms below. Now you'll need to make your way along the western path, through the laboratory, and down the tunnels until you reach Galvino's room in the northeastern most area of the map. Make your way through the conversations, and The Devil of Caroc, a soul trapped within a Golem's body, will offer to join you in your search for a soul that can get you into Durgan's Battery. Say that you need her, and you'll be given the option to purchase her for 500CP from Galvino. Accept the price and she will join your party. Picking up this character will trigger the side quest, The One That Got Away.

 

And she is an *awesome* companion. She is now sticking with my party...forever.

Cheers for all the info. Is she any different from a normal rogue? Like does she have more DR/Deflection?
