Loki can easily create a distraction however he chooses, as the majority of people in the area are intoxicated and enjoying the night. Marcellus Ver will be around the Feasting Quarter, where he can be spotted drinking wine or talking to the guests. Occasionally, he can even be seen autographing things for his "fans."

Geralt can successfully slip into the storage area behind the Sun Petal. Here, he'll find many flowers and other plants unique to Ikorr, as well as common plants imported from elsewhere. He'll also see a bookshelf where the botanist keeps his reference books on hand. Due to the dust and glitter throughout the night, it'll be easy to spot that one book is missing.

They can choose to try and track down the missing book themselves immediately or they can confront the botanist directly about it first.
