Speak with Yuka Screwspigot in the Burning Steppes.
Although my little brother Ribbly has been worthless his whole life, I think, finally, he has some value! But... we might need your help to capitalize on Ribbly's newfound worth.
My sister Yuka has been looking for him for weeks, and tracked him to the Burning Steppes. She sent word to me, asking for some hired hands.
So, what do you say? Want to help? If so, then speak with my sister. You'll find her holed up in Flame Crest, a cave northwest of Dreadmaul Rock.
