So pretty much when you complete all of your quests in the Molten Front (and if you are on the path of the Druids of the Talon) you know that you pick up the quest Into the Fire. If you don't want to wait for the druid because he's very slow, you can go to the edge of the fire on the extreme left side and avoid getting killed. Once you're at the Pyrelord, kill him like normal and you'll get credit for the quest.
