This is a limited repeatable quest which can be repeated 50 times
You need to be able to speak gnomish for Mad Mattie to talk to you. You need to do this quest at least 5 (five) times to get the next quest.
Mattie, the gnome responsible for setting up the fireworks displays for Tinkerfest, has a small problem with malfunctioning clockworks loaded with fireworks which are self-replicating themselves and threatening to overrun Steamfont. I have offered to help destroy some of them.
Disable 10 Erratic Tinkerfest Clockworks before they cause harm!
