Detailed Walkthrough
A Vision of Obscurity

To begin this quest, locate the Order of the Eye Dispatch at any Mages Guild hall. It hints at a shocking discovery made by scryers of the Order of the Eye, but fails to go into much more detail. To find out more, you must seek out Skaldir at the Mournhold Mages Guild.

When you arrive, he is busy examining a bookshelf, but turns as you approach:
:''"You read my letter? Oh, I'm so grateful you've come! We found something powerful. A Daedric—wait, what's happening?"''
Unfortunately his explanation is cut off, as at that moment, his shadow comes to life and stabs him to death. Bonafryd runs over, and now you must talk to her to ascertain what is going on.

Apparently a number of the scryers have been having visions of some obscure Daedric artifact. Bonafryd wants you to warn the other scryers before they suffer the same fate as Skaldir. Adeber Loumont can be found in Shornhelm, Wenridil is in Marbruk, and Neelo can be found in Stormhold.

Warning the Scryers
At the Shornhelm Mages Guild, you come across Eloic Montieu, who informs you that Adeber has stepped outside. You can find him behind Merethrin's House, slumped against a barrel, already dead. Collect his journal to learn more about his scrying techniques. At this point, you have the opportunity to return to Eloic Montieu to deliver the sad news. Once that is done, you can move on.

In Marbruk, Wenridil can be found on the patio behind the Queen's Residence. She moves off as you approach, accusing you of leering at her. At the same time, her shadow comes to life and starts attacking, but she manages to escape. You will need to defeat the shadow and catch up with her. Inside the Marbruk Mages Guild, Wenridil can be found hiding behind a plant pot. She thinks that the shadow may have ripped off part of her animus, but nonetheless is grateful for your help. She directs you to another planter, where you can find her logbook.

Neelo is down by the river just to the east of Stormhold Wayshrine. He warns you away, saying he will not die like the others. You can either Intimidate him into lowering his wards, or locate his sister Xarei, who may be able to convince him. She can be found by the market stalls in the center of the city. Once Neelo has been convinced one way or another to lower his wards, he will direct you to his journal, located at the root of a nearby tree.

The Psijic Obscuros
Once you have found all three scryers, a projection of an Altmer named Lilatha appears, asking for you to speak with her. She explains that she is a member of the Psijic Order, and has also been looking into the same Daedric artifact that the scryers have seen. In order to find out where the artifact is located, she explains that you need to reconstruct the Psijic Obscuros, by collecting a Liminal Lens from the Howling Sepulchers in Craglorn, and an Anuic Lantern from a shipwreck south of Eagle's Strand on Khenarthi's Roost.

When you arrive at the shipwreck, you find that bandits have already looted the Anuic Lantern, and have taken it to Hazak's Hollow on the other side of the island. The lantern can be found in a freshly-packed crate in the back of the cave. The Liminal Lens is located inside the Ancient Priest's Coffer in the Dragon Priest's Burial Chamber at the far end of the Howling Sepulchers. You must criss-cross the ravine from the south side, around the northwest side, to the east side in order to reach it.

Once you have collected both items, head to Vulkhel Guard where Lilatha's boat is waiting. It can be found on the far side of the outer harbor wall, but Bonafryd is already there. Talk to her and find out what she wants.

The Isle of Dranil Kir

Apparently Bonafryd has been tracking you since you left Mournhold, and now wants to come with you. You need to decide whether or not to bring her along.

If you decide against it, she sends you on your way and you arrive at Dranil Kir alone and in the rain.

If you agree to bring Bonafryd on the boat, she arrives with you but gets sea sick and tells you to go on ahead.

Head up the path to find Lilatha, then follow her inside the nearby ruin. 

Lilatha heads towards the Obscuros, and is suddenly attacked by her shadow. After the shadow has been defeated, Bonafryd reappears and attacks as well. It turns out she is behind the shadow attacks, and summons another copy of Lilatha's Shadow. You must defeat her in order to save both Lilatha and the device.

Finally, you are able to reassemble and activate the Obscuros. It shows you a projection of a fabricant, Sotha Sil's Clockwork City, and an unknown Daedra. Talk to Lilatha for further interpretation, and a reward for your assistance.

Notes
As with The Missing Prophecy, the events of this quest appear to foreshadow future content for ESO. In this case, the events of the Clockwork City DLC.
Once this quest is completed, Lilatha will be available to give the quest To The Clockwork City, although she will not start it automatically.
If you complete the quest without the book being read, a copy can be found in the Bangkorai Garrison in Bangkorai.
If you have a quest which requires you to kill a number of daedra, the shadows will count... as will Bonafryd.
