Back to Velen
This quest takes places in Crow’s Perch after the Bloody Baron tells you that Ciri stayed there for a few days. She’s gone now but little Gretka, who Ciri rescued, can still be found in the kitchen.
Across from the kitchen is the room where Ciri stayed. Enter Ciri’s room and use your Witcher senses to investigate. You’ll find a Spinning Top, Ciri’s Clothes and the book The Natural Obscurity of Curses. Read the book to find out that Ciri was researching curses.
To complete the quest head into the kitchen and talk to Gretka. She’ll show you a special gift that Ciri left her, a green stone. Give her the Spinning Top to complete the quest.
