Clear out the enemies in this area and have a look around the circular room.
If you follow the Ghost of Rielus, he'll walk towards your next goal. There is also a locked chest just down the hall from where the Undead Blade was patrolling. You can also find some Ancient Blade weapons and armor on the body so be sure to grab it off of the skeleton if you find things better than what you currently have. He asks you to free his brothers so that they can complete their duty to Tiber Septim. Talk to him to learn his background story and about the Underking who killed him and ensnared him. Kill it and the Ghost of Rielus will come out. Fight your way to a gated entry and pull the nearby lever to open it.Īfter going through the opened gate, you'll be attacked by an Undead Blade. Watch out for an arrow trap guarding a chest. After turning the first corner and going down the steps, you can find a chest on the left in a small nook. There aren't any side paths to get lost in at first.
We highly recommend picking up a silver weapon and some silver arrows before tackling this dungeon. Magic will work like normal, but unless you have a silver weapon or an enchanted one, you won't be able to hurt them at all.
Remember, ghosts can't be harmed by normal weapons.
