Yolanda
Appearance
Upon casual examination, Yolanda appears to be a normal raven, but enlarged to human scale and wearing some golden jewelry. Keeping to the posture of a bird most of the time, it takes a while to realize that she can take on a more human posture when she feels it's necessary and even has small, taloned [sic] hands hidden under her wings' primary feathers. She has sharp eyes, a sharper beak and an even sharper tongue.
Events
Yolanda is located in the Red Apartment, one of the locations where the stairs to Qytat a'th Lundrues appears. As a result, she is quite frustrated by all the Hermaphrodite Gryphon traffic. Yolanda offers sex, so long as she gets to be on top. If the player wants to be the one on the giving end, they must bring her one of three items. There's a Raven Key Fob and Jewelry Box which can be found thought scavenging, hunting or Outside Exploration. The player may also finish the Pirate Gold quest and give her the treasure. Each item allows the player one turn on top and none of them are repeatable.
If the player has submitted to Yolanda at least once and you have brought at least four survivors back to The Grey Abbey Library and Bunker, you may offer to move her there as well. The player will be attacked by a Harpy on the way and must defeat it to complete the move. Losing means Yolanda's treasures are stolen and she will leave, never to be seen again, to attempt to recover them.
Notes
Yolanda has a variety of scenes with Icarus if he is submissive.
