Speak with Shoni the Shilent in Stormwind.
Perhaps... Perhaps you can help us in the battle for Gnomeregan.
In Stormwind you will find the commander of our underground assault crew, Shoni the Shilent. Shoni needs assistance with her gyrodrillmatic excavationators.
You will probably find her amongst the dwarves in Stormwind.
Good luck, [player].
