Slay Grolvitar the Everburning.
Land's sakes, pardner! You done shut off those valves but good.
Unfortunately we've had a critical blowout in our gosh-darned central burnoff regulator! Missus Darla's done sent as many workers as she can rustle to go shut it off, but those flames have a mind of their own!
Literally! They're hoppin' up and grabbin' anyone who comes near! So Darla says if you can muster up out of that cave you're in and beat that elemental, she's got a mighty fine prize in store for ya!
