So guys, took us a while but we figured it out. First steps! Build a house. The requirements are as follows: Backdrop (aka wood or stone wall) Walls and ceiling as high as you can reach standing on the ground Source of light (a torch) A workbench A table and chairs A door You may not have to put a table or chairs, but it generally makes the place look nicer. Second steps! You need at least 50 silver between you or the people on your server. Finally! Once all that is done, he should move in soon. NOTE: Watch out that the guide does not move in to the house. If he does, build another one.
