Jezzle’s house is directly to the southeast of the guild spar in the swamp.
Enter it and go up the stairs to the left.
You will see a side passage leading to apparently nothing.
Go to the farthest part of the wall possible and you will be in the secret room.
There is a statue blocking the way to the lower section.
Say “immortal” to remove the statue.
There is a door in the lower area but currently there is nothing there.
