 * Prerequisite: The Throat of the World
 * Quest Giver: Paarthurnax
 * Reward: The Elder Scroll
 * Reputation Gain: N/A

Paarthurnax
Talk to Paarthurnax and ask him about the Elder Scroll. Paarthurnax will tell you if you return with the Elder Scroll, you shall meet Hakon, Gormlaith, and Felldir, the Nords who know the shout to kill Alduin in ancient times.

Arngeir/Esbern
To learn more about the Elder Scroll that you need, you can visit High Hrothgar and speak to Arngeir or you can talk to Esbern at Sky Haven Temple. They will both direct you to The College of Winterhold.

College of Winterhold
Travel to The College of Winterhold, you will be met by an Altmer named Faralda. Assuming you have not already joined the College of Winterhold faction, you will be prevented from entering the college. There are several options for getting in to the college:
 * Persuade: You can persuade her into letting you in.
 * Test: Take Faralda's test by casting the random spell that she asks you to cast.
 * Shout: Tell Faralda that you are Dragonborn and show her a shout.

Do one of these and she will let you into the college. Once you're in the college you will need to find an Orc named Urag gro-Shub, who runs The Arcanaeum inside the college. Ask him about the Elder Scroll he will place two books for you on the table. (If not working check Notes). Tell him the Ruminations on the Elder Scrolls is incomprehensible, and he tell you that the book was written by an expert on the Elder Scrolls, Septimus Signus. He gives you the last known location of Septimus.

Septimus Signus (Quest ID# missing)
You must go to Septimus Signus's Outpost, the northern iceberg where Septimus has made his home. Climb down the ladder to find Septimus working on a Dwemer Box. Ask Septimus about the Elder Scroll, and he will tell you that you must go to Blackreach, a large underground dwemer city that lies under Alftand. He will give you the Attunement Sphere and the Blank Lexicon.

Alftand
The next stage of the mission will take you to Alftand, leading on to the underground world of Blackreach. This is a long, hard mission, with lots of Falmer and Dwarven automatons. Blackreach itself has many side-missions, so you'll be on-the-road for a while. It's a good idea to make sure you've stocked up on potions, and stowed any unwanted items at home to free up space for your lootings.

Alftand is located on the glacial mountains southwest of Winterhold. When you enter Alftand you will need to travel throughout large glacial tunnels, these glacial tunnels were left in a hurry so there are tools laying all over the ground. Follow the tunnel till you reach the Dwemer Ruins. You will come across a door that can be unlocked from the other side, so go to the passage that heads west up a ramp.

Carry on going north, there will be two Dwarven Spheres. Kill them and head through the gold door and up to a Dwarven Spider–infested passage stretching south. This main passage will lead you east, about the room with the Dwemer Sphere's in it, but you are now on the ledge above it, and you will have to dodge the pistons. This will lead you to the Alftand Animonculory.

Travel through the Alftand Animonculory you will come across a massive shaft in the Anionculory. Travel down this shaft and you will come across some Falmer. Dispatch the four Falmer that reside of the shaft. Once you're at the bottom you will find an entrance to a gold door. This door is guarded by fire jets; get past them. Enter the door - which leads to a Falmer nest (though it is not necessary to walk through the fire jets as on the left side there's a little gap between the pipes you can walk through without worry of being burned). Go through the nest, dispatching the Falmer inside. Go though the golden door on the southwest over a bridge. This will lead to another looping walkway with several Falmer and at least one Frostbite Spider on it.

Now enter the Alftand Cathedral. Battle the two Falmer. Travel up the Stairs and activate the switch. Then pass through the gate which was once shut. You will find a Dwarven Centurion that you must kill, as he has the key you need to proceed. (An easy way to defeat the Centurion would be to have your partner stand at the front of the gate, activate the Centurion, run up the stairs and close the gate. On the outside of the gate,you can easily defeat the Centurion with a bow and arrows.) Next, go to the gate on the southwest, you will hear an argument of two adventurers, Sulla and Umana. They will fight if you wait in concealment, but you will need to kill the survivor or both of them. Go to the Dwarven Mechanism now, and insert the Attunement Sphere Septimus gave you. The floor parts, revealing stairs down to a hidden gold door and an entrance into the mysterious undercity of Blackreach.


 * Note: At this point the elevator immediately behind the "Dwarven Mechanism" will take you back to Skyrim. This lift can then be taken back to this point if you are struggling for space with all the loot. Also a useful midway point for returning later to collect the various bits of Dwemer metal for converting to ingots.

Blackreach
You can exit Blackreach using the appropriate Dwarven Elevator just left of your location. Just take care of the Dwemer sphere and the falmer, and follow the cobblestone path southeast to a golden button encased on a Dwarven head pedestal. Press it, and the elevator behind lights up, allowing you to ascend and exit back outside. Open the gate, allowing you to enter from the Great Lift of Alftand.

This is a large city with many enemies and things to loot. To continue the mission, follow the quest marker to the far southwest corner of the map. This will lead you to the Tower of Mzark, the place where the Scroll resides.

Oculory Operation
Once inside the Tower of Mzark, you will come to a room with another dead man. Proceed through the gold door and you will be in a room with a spiral stair case, follow it up to an Oculory. Go up to the controls. The controls consists of a Lexicon Receptacle and four positioning buttons embedded in pedestals.

Activate the Lexicon Receptacle, so the Blank Lexicon rests on top of it. The two pedestals to the Receptacle’s right, the only ones currently active, open and close the Oculory lenses. Press the taller of the two pedestals (right of the middle one with the lens chart on it) three or four times, until the pedestal with the blue button to the left of the middle one starts to glow. Move to this new pedestal (at this point, the Blank Lexicon may be glowing blue). The two pedestals to the left of the Receptacle, the taller of which is now active, control the ceiling lens array. Press the button of the taller, left pedestal twice, until the button on the far left, smaller pedestal begins to glow. Now press that button, and a large set of lens crystals descends from the ceiling and stops. The main crystal rotates and splits apart to reveal a tubelike carrying device.

Once you get the scroll you have completed the quest. Pick up the Lexicon in order to continue the Discerning the Transmundane quest. good job

Bugs

 * It is known that if you complete all the quests for The College of Winterhold before having talked with Urag gro-Shub about the elder scrolls, you will not get a text option to ask for the books about the location of an elder scroll. The proper text option has a slim possibility to appear after all available chat options have been selected. This bug appears if the player has already spoken to Septimus Signus. If you have already talked to Septimus Signus you can skip talking to Urag and continue on to Alfrand, southwest of Winterhold.
 * (360) Esbern may not talk to the player if you go to Sky Haven Temple. He just stands there and gives generic dialougue, forcing the player to go to Arngeir.
 * There is the alternative way to complete this quest. Go to just north of the College there is a cave named Septimus Signus's Outpost. Septimus will give you another quest that allows you to get the Elder Scroll then continue the story.
 * If you have already completed Septimus Signus's quest go to Blackreach to the Tower of Mzark and the scroll will be there, inside the center of the large dwarven sphere artifact.
 * There is an error showing on the map, on the path finding the Elder Scroll as well.
 * If you are in the middle of the Staff of Magnus quest, there will be no text options for Urag, only the simple guard-like talk about the eye.
 * When walking up towards the Tower of Mzark, a door inside will be missing. If you choose to open it, you will not get past the invisible-barrier.
 * Sometimes when the quest is finished and the marker appears on the scroll, it still does not allow you to pick it up. If this occurs, you must go back down the elevator to Blackreach and then return back to the scroll chamber, you should be able to pick it up now.
 * While in Blackreach, if you wait your follower may be in a position as if he/she was downed. To fix this, all you have to do is leave the area.
 * [PC][360] There is a glitch in Blackreach where, after taking an elevator to the surface, the screen fades to black repeatedly and may erase autosave files, recommended to manually save before activating elevators to the surface.
 * [PS3] Even though you can. Continue the quest as normal, the current objective might not be in your quest log, but will be on the map.
 * [PC] If you have completed both the College's quests and those by Septimus, don't have the Elder Scroll and Urag doesn't give you any quest dialog towards the Elder Scroll, you can jump start this quest line by using the consol to create the scroll in your inventory. The cube at the Septimus Signus's Outpost was closed, and the device in the Tower of Mzark can't be used a second time... leaving the console creation the only option. player.additem 0002D513 1 will place it in your inventory.
 * [PS3] After obtaining the Elder Scroll and taking the elevator lift to "Open Skyrim", the gate and enclosure you find yourself in after the loading screen will not allow you to exit and leave the Alftand Ruins. There is no floating marker or any text signifying you can unlock the door/gate. The only way to exist is to take the lift back down through the Tower of Mzark, backtrack through Black Reach and back through the Dwemer ruins to the original point of entry. This is probably due to the player not picking up the lexicon for Septimus Signus where they had originally placed it. Go back into the ruins, pick up the lexicon and take the lift back up. Your map should now update and a lever should be to your right to open the gate.
 * [PS3] Rarely, Umana will attempt to talk to you, and diolouge box will open. As she has nothing to say and no options to give, the game will freeze.

Easter Eggs

 * When Urag gro-Shub tells you about the Elder Scrolls, he mentions that "All of it is true. Even the falsehoods. Especially the falsehoods. This is very likely a reference to the Star Trek: Deep Space Nine episode "The Wire" in which the character Garak says "All of it is true. Even the lies. Especially the lies." When asked if the answers he gave during questioning were true.
