trondale
there's a lever behind the drawers that are not far from the closet

I also have a question on this quest, hanging stage to decide what to do with the book on necromance which but when it is read the option of action only two to remove or leave alone, what to do with it? Tell me how it's going to be.

Kazuma Sato
read or give to Gayle, he'll eat it (if you're friends with him)

Ilya Liapin
How do you read it? I can't figure it out, and Gail asks you to open it first, I can't figure it out.
UPD: understood in the well was the answer)

Kazuma Sato
What's the answer in the well?

reddoor
The stone next to the spider that needs to be inserted into the book

Grozniy
Okak is running with me! I went through all the stones, but I didn't see the spider...

reddoor
there's a big spider strong, under it on the tier below lies the right stone

Kazuma Sato
Thank you! I banged this grand madam earlier, but I didn't go down to her lair. It's OK now.
