I begin my journey at the Great Tree of Elden Root. The air is warm and sweetened by the smell of smoked meat, because of Bosmer and their carnivory.

My journey was simple: Walk to all of the Alliance capitals, starting at Elden Root, passing through Mournhold, then finally trekking to Wayrest. It was a journey once thought impossible, but I may have found a way.
I hiked north toward Cormount, passing the gate into Northern Elsweyr. I take the road that leads through the Tenmar Forest. I fight off Senches and Harpies through the warm jungle. I wave to the Khajiiti farmhands as I pass by Merryvale. Near Hakoshae, I hear the roar of a dragon flying overhead. I pass through a gate to a long winding trail, with Blackwood on the other side. It's still warm here, but it's a lot wetter. This is truly the nicest portion of Cyrodiil - no Alliance War going on here, and plenty of moist swamps. I pass through Leyawiin before heading east, crossing the Cyrodiil border with Black Marsh and entering Gideon. There is a road north-east of Hutan-Tzel that crosses a shallow lake and leads into Shadowfen. I swing by Hissmir to flirt with Gentle-Heart but she is still too busy with the several tons of fish she accrued just a few weeks ago during New Life Festival.
I almost never follow the roads in Shadowfen and always find myself stuck somewhere that I have to go around, but that's how it goes, being Fen-Wander... wandering the Fen. Stormhold is the next town I visit before heading toward the Morrowind border.
Soon, after passing by Deepcrag Den, I see off in the distance the magnificent city of Mournhold!

As I continue north-west, I near the town of Serk, and the smell of brimstone is starting to be apparent. Better than the smell that hit me when I first visited this town so many years ago - that of death, fear and the Llodos plague. After crossing into Stonefalls, it is a near straight-shot north to Fort Virak. As I get closer, I can feel a cool breeze fighting against the warm front from the volcanic climate of Stonefalls. I take the marshy underpass to avoid entering Fort Virak itself, since it still smells a bit like zombies, and the trees are changing to an autumnal color.
I am now in Skyrim and soon I pass through Riften before continuing north. I bully some bandits at Fort Greenwall on the way toward Windhelm. As I head to Windhelm, I approach the bridge leading to the city - and then take a left to head to Voljar's Meadery. There is a roadway that leads north-west, to this building...

Inside, I go to the basement. The last Wardrobe on the left is a secret passage that leads to the legendary Blackreach.

At the west end of the cavern of Mzark is a Dwemer ruin that leads to the Greymoor portion of Blackreach. I stay in the south and continue west through some of the prettiest scenery in Tamriel. I pass by Dark Moon Grotto before entering Arkthzand Caverns, a name which makes me sneeze every time I pronounce it. I head west toward the Library of Arkthzand and take the lift back up to the surface world. I navigate the foothills of The Reach and reach Markarth. There is a cart that leads to Bangkorai, and while I wouldn't normally count this as "walking" the entire way, since the other end is at a roadway I give it a bit of a pass. It would be nice if there was an actual road leading out of the Reach somewhere that connects it with Bangkorai, or a footpath into Craglorn, but this still connects The Reach with Bangkorai.
From there, I just hike west to Evermore, cross the bridge into Stormhaven and I find myself standing at the gates of Wayrest soon enough!

Something I would love to see in the far future, if we have a Central Skyrim, Southern Hammerfell and Western Cyrodiil zone, is an overland "highway" route that can circumnavigate all of Tamriel, with only gates and border crossings - no boats, carts or wayshrines. However, already the world of Tamriel feels more connected than ever before. I remember when each alliance was absolutely severed from each other, and even when we got to Veteran rank the version of the zones we were seeing were still exclusive to our Alliance. That changed with One Tamriel, but ever since Greymoor and Blackwood, there has been even more connection between the zones.
I'd like to see roadways into Alik'r, and the northern edge of Blackwood seems to have a roadway that leads to the Bravil portion of Cyrodiil. There are tantalizing hints of more overland connections to be made. But I hope you all enjoyed this journey I shared!
