She resides in the "secret" room on the ground floor at the southwest part of Draynor Manor, just behind the hidden door next to the bookcase. To get to her search the candle sconce on the west wall of the study, revealing a "secret door" which takes the player into the bedroom. Ava will not appear until the player has completed the Ernest the Chicken quest. To exit the bedroom players must pull the switch, opening the door and allowing the player to leave.
Ava also has a small shop, Ava's Odds and Ends, that sells various feathers, arrows, and arrowheads. However, players must have completed the Animal Magnetism quest before they can access this shop. This is handy if a player needs to quickly buy the 75 steel arrows needed to upgrade their device.
She sells the attractor for 999 coins and if the player asks why, she says that 999 seems less expensive than 1000. This is exactly what happens in the modern market, things being sold in the ".99" to make it appear cheaper.
During the Ernest the Chicken vs. Professor Oddenstein court case, Ava tells the player that she is currently researching "necroballistics." This is most likely a combination of necromancy and ballistics and explains why her attractors use undead chickens to bring back ammunition.
When players attempt to use a feather on her she says "What are you doing? I'm not ticklish."
While wearing the chicken set from the 2007 Easter event players will have an amusing conversation with Ava. (The entire set must be worn, similar to how Flap's enhanced emote doesn't activate without the full set.)
