How to get the Lucid Nightmare mount (World of Warcraft: Legion)

The Lucid Nightmare is a new mount added to World of Warcraft in patch 7.3. It is a "puzzle mount" just like the Riddler's Mind Worm and the Fathom Dweller mount that requires you to solve a long series of puzzles in order to obtain. Just like these mounts, getting the Lucid Nightmare mount by yourself is an almost impossible task, but if you follow this guide then it should be easy enough.

This guide is made so that it should be easy to follow the step-by-step guide. However, if you for some reason get stuck, just leave a comment below, and I'll try my best to help you out.

Step 1) Go to Curiosities & Moore in Dalaran

The Curiosities & Moore in Dalaran is just next to the A Hero's Welcome / the Alliance base in Dalaran. Head upstairs and click on the Inconspicuous Note that lies on the table in the main room. This note provides the first clue of the puzzle, and reads as following:

"It begins in the 2104059.
With a most pleasing sign.
(These letters will not always rhyme.)"

Step 2) Head to Ulduar

Now take the Portal to Wyrmrest Temple and head towards the raid instance Ulduar in the northern part of Storm Peaks. Enter the instance and go to the north-western corner where you fight XT-002 Deconstructor. Kill the bosses leading up to him and XT-002 Deconstructor himself, and look for a Rusty Lever in the pile of scrap parts.

This can be clicked on to spawn a 20x20 grid of lights on the room. These can be clicked on, and you have level to click on a certain pattern in order to progress to the next step of the puzzle.

It is pretty difficult to explain which lights to click on, so follow this picture. Clicking on all of them can be a bit time consuming, so prepare for that.

By doing this you get to activate another note, this time it reads the following:

"1000 years imprisoned.

Surely it wears on the mind."

This refers to C'thun in AQ40, so head to Silithus and enter the instance.

Step 3) Ahn'qiraj

When you are in AQ40, kill bosses and get to the end of the raid instance. At the end of the instance you will find a clickable Mind larva that needs to be interacted with. Upon doing this you will begin to play a minigame of Bejewled.

To win you need to a certain score, but there's no visible score, so you just have to keep playing until you get it. There is no good strategy for this, but just keep playing and you will most likely win fairly soon!

Once you win, another note will spawn:
"Deeper than deep.

Awaits your seat."

Step 4) Deepholm & Shadoweave mask

For the next part, we either want a tailor to help us out, or to head to the Auction House. For the next part you will need a Shadoweave Mask, and these are most likely very expensive to buy at the moment. However, if you got a tailor you only need to get your hands on 2 Bolts of Mageweave, 8 Shadow Silk and 2 Heavy Silken Thread, and you're good to go. The recipe can be dropped from any Dark Iron Dwarves in Searing Gorge, and should be fairly common.

When you have this, go to Deepholm and head south (/way 58 25 Crumbling Depths). At this location you will find a fissure (/way 63.76 22.51 Dark Fissure) that you can click on. Drop into the fissure to continue.

You will encounter a Dingy Plaque at the beginning of the Deep Cavern that reads the following:

"Supremacy?

Get...
Shirk...
...eke..."

This is simply an anagram for "Racksum Greep is the key", which points us to the NPC Racksum Greep in Ratchet in Northern Barrens. Luckily we don't need to go there, because his clue for the puzzle is that he wears the Shadoweave Mask, so no need to go there. Now equip the mask and interact with the skull, and a new note will appear in front of the chair:

"Where the shaded delegate may appear."

Step 5) Gnomeregan

This note is a reference to the Dark Iron Ambassador in Gnomeregan, so this is where you should head next. Follow the red lines in the image below:

 This will lead you to the 10 levers, and above these a small interactable button called "Instructions" will be clickable. This gives the following message:

"01110111 00100 10010110 10101
11110111 01100 01111111 01000
011010111001011010010110 10111101
11001 00111111 10010 01001001
10000 011010010110100111010110
01011011 11110 11110001 11111
11100000 00010 11111111 01000
10110111 10101 01111111 00001
10101110 11111 00110000 01000
101101010010101110010110

180

+1111111111"

If you decode this you get a reference to 3 battle pet abilities: "Falling Murloc", "Mighty Charge" and "Eye Beam". However, this does not really matter to us. What you need to do is use the following two macros to set the consoles to 1222176597:
Up: /script SelectGossipOption(1)
Down: /script SelectGossipOption(2)

You can of course do it without the macros, but that will take a much longer time. Doing this spawns another note that reads:

"Games and toys are left behind.

When you awaken screaming."

Step 6) Val'sharah

This clue takes ut to  Ash'theran in Val'Sharah (/way Val'sharah 66 36.5). Here you will find a Nightmare Tumor that can be clicked on. This will spawn a mini game where the objective is to turn all the lines blue by clicking on the dots. This can be a bit difficult, but it should be doable in a few tries. By completing this a new note will spawn:

"What you seek is buried within."

Step 7) Kun-Lai Summit & The Endless Halls

Use the following TomTom Macro to get to the Tomb of Secrets in Kun-Lai Summit: /way Kun-Lai Summit 53.4 49. There will be an urn at the base of a Mogu statue there, and this urn can be interacted with. Doing this will give you a warning, and you obviously need to accept this. 

This teleports you to an area called "Endless Halls", and you need to figure out how to get out of there. This can be pretty challenging, since most rooms look exactly like each other. The best method to complete this is to draw a map (by hand or in Paint).

The Endless Halls have areas with orbs that give you a buff, and you need to find a rune for the corresponding buff (example: red orb = red rune etc.). There are a total of 5 runes you need to click on (red, blue, purple, green and yellow), and once you've got all five done you will get teleported to a room with the next note:

"The way is now open.
To the greatest secret never told.
A fitting end to your journey."

Step 8) The Forgotten Crypt

You might be thinking about giving up by now, but this is actually the final step in the journey to get your Lucid Nightmare. Just head to the forgotten Crypts, an area just next to Karazhan (/way Deadwind Pass 39.85 73.6). This is a large area that have never been used for anything until now, but this area has the Puzzler's Desire treasure chest that contains the mount! 

It might be a bit challenging to get to The Pit of Criminals where the treasure chest is located, but keep descending down into the crypts and you will get there eventually. At one point you need to swim underwater to find a secret passage, but once you've found that you are just a minute away from your new mount!
