If you hadnt taken the journal from the dead woman not far from the entrance, you will have to use trial and error to solve the puzzle. You battle your way through this falmer invested cavern(the falmer here have unique hardened falmer armour) and progress throughout until you reach a puzzle near the end of the area. Upon entry you hear a woman's voice and a ghost of a woman appears telling you her story of her search for the legendary Aethetium Forge and her unfortunate demise. You will need to bring a crossbow or bow with you in order to advance through this location, or find one in your travels(there is a unique bow within that is pointed out to you.

I am not sure entirely if one can be found within shops or the College of Winterhold yet however. The other way to start this quest is to find the non-skill book called Aetherius Wars, that can be found within Fort Dawnguard on the ground floor, another copy can be found on the roof of the fort and others are scattered throughout the world. You can either discover the location of Arkngthamz(thanks Bananaster) that can be found directly south east of Dushnikl Yal, the Orc stronghold in the south of The Reach. This quest can be started in two possible ways. This achievement is rewarded for completing a side quest which involves finding the four pieces of the Artherium Crest and discovering the location of the legendary Aetherium Forge.
