Royal Stonecutters Union (a.k.a Royal Stonecutter's Guild) is a dwarven organization of stonecutters, similar to the human Stonemasons Guild, seen operating in Ironforge and Stormwind. After Deathwing's return, they set up Slabchisel's Survey in the Wetlands.
Their most famous tasks, or works they've been involved in, are:
- Removing a wall of the Stormwind's Canals with explosives and building the gatehouse and the road leading down into Stormwind Harbor
- Building the memorial for Sully Balloo
- Recovery and repair of Danath Trollbane's statue in the Valley of Heroes
- Investigating the damage done to the Stonewrought Dam
