- In a Cave east of The Crossroads - Go east along the road from The Crossroads and it will very quickly turn into a ravine. At the bottom of the ravine is a cave entrance. When you go in, Geralt will remark that it's a ghouls nest. The diagram is in a chest in the back of the cave, next to one of the dead guys who inhabit the lovely cave.
