Kaddock asks around and the neighbor's story doesn't change. They all figure that the glassworks is working on some kind of secret project. It's not normal for them to be closed up like that but with the plume from the furnace they figure everything is operating as normal.
Knocking at the front door doesn't seem to do anything. Even after repeated attempts and sufficient time to wait nobody comes to even poke their head out of the curtains to see who is at the front door.
The party considers there options and a few ideas come to mind:
- Pick the front door lock - 4 successful DC 25 Thievery checks
- Break through a window - no check needed but will make a lot of noise and draw attention from passersby
- Break down the door (as the window but will take longer)
- Head to Kaijitsu manor to try to talk to one of the nobles there to get a key
- PIck the back door lock - same as #1 but enters from a different side
- Climb the wall (DC 20) and look for an entrance on top
Of course this is not all encompassing.
