The troggs are not the only thing that interested Magatha in Ragefire Chasm. She has heard word that one of her servants, a Maur Grimtotem, found something peculiar while in the Chasm, but he never made it out to show her what. She'd like Maur's body found--if it still exists--and any signs of what he found while attempting to speak to the troggs. Return to Magatha any items of interest, and I'm sure she would be very generous in her reward. Again, seek the Chasm in the darkest areas of Orgrimmar.
