I been investigatin' our corrupted Bloodtalons troubles and I think I've found da source. A lone naga. He was holdin' a red orb aloft over our hatchlings and I could see dem... changin'. I'm certain he tinks his thievery and spellcastin' have gone unnoticed, so ya should be able ta catch him unawares. Kill dis naga and bring me back dat vile orb - you'll be findin' him to da northwest, at Zalazane's Fall.
