Zone: Sunless Barrens Spoiler: Solution to the Monolith/Door Puzzle Spoiler: The Door The door is located at location 311.9, 54.5, -237.3. The door has plaques on it that give you the clues to open the door. Hover your mouse over the plaques, to find the following clues: A wise man in his final days proclaimed with heated passion, that the world would drift aimlessly without the biting of the gadfly The clues on the door indicate the order in which you have to activate the monoliths: "A wise man in his final days" - a person in the final days is close to death. "proclaimed with heated passion" - heated passion refers to fire. "that the world would drift aimlessly" - drifting (such as adrift on the ocean) refers to water. "without the biting of the gadfly" - a gadfly is an insect that flies in the air, so this refers to air. Spoiler: Locating the Monoliths, Activating Them, and Opening the Door The monolith locations below are listed in the order in which you have to activate them. Click on the monolith to activate it (when activated a light will continuously stream from the monolith and into the sky). If you are not activating the monoliths in the correct order, they will not stay activated. Once you have activated all 4 monoliths in the correct order, the door shown above will open and you can claim the treasure (which is typical chest loot). However, if you wait too long after activating the 4 monoliths, the puzzle will reset and the door will close (so go to the door immediately after you activate the monoliths).
