This is an easy quest, you need merely kill all the monsters in the den. There are usually around 50 of them, depending on the random spawn and size of the Den. When you get down to five left the Quest Button will pop up telling you that, and the display in the Quest Window will count down the remaining kills.
'''Tips: ''' The only potentially tricky part is if you miss a monster, often a Fallen Warrior that will run when you kill something else and get lost in a corner. Clear the Den systematically; be sure you've gotten everything in one area before you move on, especially running [[Fallen]], and you won't have to waste time hunting all over the place for that one last monster.
'''Trivia:''' There's a cute Easter Egg in the Den; if there are fewer than five monsters remaining (few enough for the quest prompt to pop up) and a [[Fallen Shaman]] resurrects enough Fallen to increase the number above 5, the quest window will display, "Monsters remaining: 666."
