According to Arano, Ashfallow Citadel has been abandoned for a long time, but when you arrive at the scene you will find the two Redoran Guards dead and be attacked by two [[Dragonborn:Morag_Tong_Assassin|Morag Tong assassins]] immediately. Dispose of them and enter the half-buried ruin. The interior is almost entirely covered in ash and the very first chamber hides an [[Dragonborn:East Empire Company Strongbox|East Empire Company strongbox]] on some shelves.
Kill the patrolling assassin and proceed down the spiral staircase. Loot the chest here, and find the narrow tunnel leading south. Before long, you will land in the private quarters, patrolled by two assassins. The path ahead is blocked by a set of metal bars. A bookshelf in the western room contains a safe with especially valuable loot. The eastern room contains an [[Skyrim:Arcane Enchanter|arcane enchanter]] and an [[Skyrim:Alchemy Lab|alchemy lab]], as well as a chain you need to pull to proceed.
If you didn't kill her earlier, [[Dragonborn:Mirri Severin|Mirri Severin]] will be waiting for you along with several assassins, so fight them all and face two more sets of metal bars blocking the path. Head into the western room and jump over five [[Skyrim:Traps#Bear Trap|bear traps]] and pull the chain. The other chain is located right next to the metal bars. Once they are removed, a third set of metal bars will block your path and the hallway will be plastered with [[Skyrim:Traps#Pressure Plate|pressure plates]] triggering [[Skyrim:Traps#Spiked Wall|spiked walls]]. Head into the western room and avoid more traps, then pull the two chains in there.
