Om City Dwarves

This story begins with our PCs, a trio of young dwarves, living in a city. They're the children of cobblers who perished the month prior when plague swept through the city. Coming home from the funeral, they have found their shop ransacked. Tools broken, shoes in for repairs ruined, the whole place a mess, except for one left boot that has been repaired and left in the middle of the room. Obviously this was the work of a rival cobbler shop, but which one? And why? Soon enough the clients stop coming in. No new orders for shoes, boots, or even sandals.The potential heroes are facing a serious problem as funds begin to run out... yet some god must have smiled down upon these poor orphans, for one day they come downstairs to find all their work completed for them and the shop nicely cleaned up
