Vaatividya does some great videos about this game. I especially love his insight videos. To be fair, the path to the real workshop is actually a bit difficult to find, you would either need to know where to go or just be extremely lucky to stumble upon it. The best part of the place is you get one of the best hunter tools there, the Hunter's Bone, which allows you to flash step when you dodge, increasing your dodge window. Several of the nastiest hunter enemies in the game use this item, including the "Cainhurst Rogue Hunter" from Eileen's quest, Gerhnam, and Maria.
