Take this bag of supplies with you to Tanaris. Travel to Lost Rigger Cove, and look for a circle of stones. The eastmost peninsula is the secret... From this circle only, read from the book of Aquor; summon the only creature that can transform the items you collected into a totem to fight Blazerunner. Aquementas will not be pleased to be awakened, but remember, you must remain in the circle for him to transform the items.
