Hey. Firstly, do you know how to write AI packages, because you will need to, for him to hioffer services. With that in mind do the following: Open up Ferrum's box (I don't know what to call it but its in the window with all the objects). Then click AI. Firstly click the boxes which relate to him (so if he sells weapons, armor, etc.). Then create an AI package where he stands in the palace for a certain amount of time and during that time, click the offer services box. I hope this helped but you might wanna read a tutorial on AI in order to do this from the Construction Set Wiki. Thanks, manmanman
