If Voidfire isn't next to you, use the whistle you got to summon the whelpling. Then, interact with Voidfire at the marked locations (some chat options will appear) to get credit for the location and have your progress bar increase by 25%.

If you're like me and doing this on an alt whos never done Cata content, you dont need to unlock Vashj'ir through the story to get out there. Skyriding will get you out there before fatigue sets in, you just want to bring a water breathing pot as it does require you to swim to complete the quest
