So Glaffin's schedule should now be:
- Royal Smith Order
- 3 Engine Merchant Order
- 1 Engine Order A
- 1 Engine Order B
The Smith order will cost him about 200 crowns for material and take nine days to complete if he takes 10 and doesn't hire any help. The three engine order will take 8 days per engine, and the 10HP engines will take 10 days per engine. I'm not really sure what else to do for roleplaying here while the other PCs do their things, unless you have something in mind to throw at him, since logically he'd now start throwing himself into his lucrative work and not be going out of his way to interact with people.
One thing I can see him doing is revisiting the church of Tharius in the evenings to talk with the priests there, and the same with the Azure guild. The other party members know where his forge is, so they can easily locate him if they need to talk to him as well.
